Abstract

On the basis of verified records, the Russian Arctic liverwort flora is comprised of

205 species representing 67 genera and 26 families. Each taxon is treated with respect

to distribution and frequency within 15 phytogeographic subdivisions. A historical

review, annotations, a comprehensive list of synonyms, and a bibliography are included.

INTRODUCTION

The study of liverworts in the Russian Arc-

tic was begun in the middle of XIX century.

Important early contributions were made by

S. O. Lindberg & H. Arnell (1889), and H.

Arnell (1913, 1917), who provided detailed

descriptions of many taxa and described sev-

eral new to science. Most subsequent publi-

cations dealt with regional hepatic floras, with

the exception of the valuable treatment on

the liverworts of northern Russia, “Liverworts

and Hornworts of the North of the USSR”,

which was published by R. N. Schljakov (1976,

1979-1981) in five parts. This treatment in-

cludes a discussion of taxonomy and the gen-

eral distribution of northern liverworts. Sub-

sequently, numerous reports on liverworts in

various arctic regions were published, and

many of these are summarized in the recent

Checklist of Hepaticae and Anthocerotae of

the Territory of the Former USSR by N. A.

Konstantinova & al. (1992). However, this list

contains only general information and a lim-

ited number of annotations. Furthermore, it

includes a number of doubtful records that

could not be verified at that time.

The present checklist represents a compi-

lation of all available literature on Russian

Arctic hepatics, and incorporates the results

of a revision of some specimens that were the

basis for doubtful records. We have studied a

number specimens from various collections

from the Polar Urals (det. by L.A. Zinovje-

va), from Franz-Josef Land and the Taimyr

Peninsula (det. by A. L. Zhukova), from

Chukotka (det. by J. Duda), O.Ekstam’s col-

lections from Novaya Zemlya (det. by S. Ar-

nell), and H. Arnell’s collections from Sibe-

ria. Unfortunately, our search for voucher spec-

imens was not always successful because many

of them are scattered in various herbaria and

some were not available for study. A serious

obstacle to the production of this checklist is

that very few specimens were collected by

professional hepaticologists and determined

while alive, that is, with oil bodies present.

Therefore, our knowledge of Russian Arctic

liverworts is based mainly on dried materi-

als collected by geobotanists, “mossologists”,

lichenologists, and others. Studies of dried

material may lead to misinterpretations and

misjudgments of the taxonomy of certain

groups. Unfortunately, we had no possibil-

ity to study the majority of the collections

that were the basis for the more valuable con-

tributions at the turn of the century (i.e.,

specimens reported by Lindberg & Arnell,

1889; and Arnell, 1917). The necessity for

revision of these collections in the light of

new knowledge of liverwort taxonomy is ev-

ident; however, we consider the present study

a starting point and hope that it will pro-

Liverworts of the Russian Arctic

vide a stimulus for further studies of arctic

liverworts.

The delimitation of the Russian Arctic

and its subdivision into 15 phytogeograph-

ic regions accepted herein (Fig. 1) is that

of B. A. Yurtsev & al. (1978). In some in-

stances, it was difficult to determine if a

locality is situated within the Arctic as

delimited (for example, some localities in

the Polar Urals, Lower Lena, and Archan-

gelsk Region), and we made an arbitrary

decision to include species from such local-

ities in the present checklist. The frequency

of each taxon in each region is assessed ac-

cording to the following scale: r = rare

(recorded from 1-5 localities); s = sporad-

ic (6-10 localities); and c = common (>10

localities). Also taken into consideration are

the abundance of each species, biological and

ecological peculiarities, and whether the tax-

on could be easily overlooked. These data

on frequency are preliminary and reflect the

present knowledge of Arctic hepatics, since

the degree of investigation of different sec-

tors of the Arctic varies enormously. For

example, many regions have been explored

by nonprofessional hepaticologists only, and

such collectors rarely do a thorough job of

collecting the microhabitats. However, fre-

quency data give a general idea of the dis-

tribution of individual species, and allow

us to concentrate future investigations on

the search for rare species. Varieties are in-

cluded in the list. Forms usually are not

listed but notes on the distribution of some

forms are given in the comments.

In addition to the frequency abbreviations,

the following symbols are included in the

checklist: “!” indicates confirmation of the

presence of a taxon in a region; “?” suggests

that occurrence in a region is doubtful.

In this checklist we used the same ge-

neric concepts as in Konstantinova & al.

(1992). Some exceptions are related to vali-

dation of names (see Konstantinova & Vasil-

jev, 1993; Konstantinova & Chernjadieva,

1995) and corrections of some printing er-

rors. The authors have the differnt opinions

on the volume of genera and the current us-

age of “microgenera” is the decision of the

first author.

REGIONAL HISTORY OF EXPLORATION OF

HEPATICS IN THE RUSSIAN ARCTIC

FRANZ-JOSEF LAND ARCHIPELAGO (ZF). A

review of the bryological exploration of this

archipelago, as well as an analysis of the liv-

erwort flora were published by Zhukova

(1973a). She studied all the available collec-

tions and produced a list of 33 species and

15 infraspecific taxa. A review of this mate-

rial has resulted in the exclusion of some spe-

cies (e. g., Sphenolobopsis pearsonii, Gymnomi-

trion obtusum etc.), and the addition of oth-

ers (e. g., Lophozia rubrigemma, Scapania

zemliae, and S. ligulifolia), so that 35 spe-

cies are now known. This low number pre-

sumably reflects the High Arctic position of

the archipelago, as well as insufficient in-

vestigation of the flora.

KANIN-PECHORA REGION (KP). Northeast-

ern Europe is one of the most poorly studied

areas of the Russian Arctic. The first data (32

species) for this area were published by R.

Pohle (1915) in his treatment on bryophytes

of the Russian North. Apart from this list, only

two papers dealing with liverworts of north-

ern Arkhangelsk Region have been published;

one by Zhukova & al. (1981), and the other

by Konstantinova (1990). In the former, 21

species of liverworts collected in the course

of investigation of bog vegetation were list-

ed, while the latter is based on revision of 29

specimens collected by F. Ruprecht in 1841,

and documents the occurrence of 30 species.

In total, 54 liverworts are known presently

from this large and diverse territory, a num-

ber that clearly does not reflect the true di-

versity of hepatics in this region.

POLAR URAL (PU). The first data on liver-

worts of this region (4 species) were pub-

lished by Pohle (1915), and in 1931, Z. N.

Smirnova (1931) recorded 32 additional spe-

cies. A more comprehensive list of the liver-

worts of this territory was presented by Zi-

novjeva (1973), who listed 130 species for

the Polar and Northern Urals, including 90

species for the area referred to herein as the

Arctic. During our study, a number of speci-

mens determined by Zinovjeva were reexam-

ined and some species are excluded (see an-

notations and list of excluded taxa). More

128 N. A. KONSTANTINOVA & A. D. POTEMKIN

recently, some additions to the flora of this

region were made by I. D. Kildjuschevsky

(1975), and I. Novotny & L. Klimes (1991)

recorded the recently described species, Pro-

tolophozia debiliformis, as well as 13 associ-

ated liverworts. Two of these, Marsupella

sphacelata and Scapania undulata f. aequat-

iformis, are new for the Russian Arctic. Most

recently, 64 species from the Sob’ River Ba-

sin, including 27 species new to the Polar

Urals, were reported by Konstantinova &

Chernjadieva (1995). At present, 110 species

of hepatics are documented from the Polar

Urals, but this number surely does not re-

flect the true richness of the liverwort flora

of this area.

NOVAYA ZEMLYA (NZ). A fairly detailed

account of the history of early studies of

bryophytes of the Russian North, including

liverworts of Novaya Zemlya and Waygach

Island, was given by H. Arnell (1917). On

the basis of a compilation of published data

and identification of a number of collections,

he cited 32 species for this area. Examina-

tion of O. Ekstam’s collection by S. Arnell

(1947) enlarged this list with 19 additional

taxa, some of which were revised in the course

of our study. In spite of relatively high num-

ber of species (61 species and 3 varieties)

known at present from this region, the liver-

wort flora of these High Arctic islands sure-

ly is more rich.

YAMAL-GYDAN REGION (YG). The first re-

ports from this Region provide mostly frag-

mentary data on about 30 species (see Arnell,

1917; Ladyzhenskaja, 1971; Andrejeva, 1981),

and some common hepatics were mentioned

in several geobotanical papers. However, in

1973 to 1983 and in 1988, 1990, 1992 the group

of Polar Expedition headed by Olga Rebris-

taya has collected about 15 000 of liverwort

specimens. This collection was identified in

part by Zhukova (see Zhukova & Rebristaya,

1986, 1987), but afterwards almost complete-

ly revised by A. D. Potemkin (1993). His an-

notated list (l.c.) included 121 species, two

of which, Gymnocolea fascinifera and Pras-

anthus jamalicus, were described as new spe-

cies, and 35 infraspecific taxa, with two new

forms of Tritomaria described (see Potemkin

1990, 1992a, 1993). Two publications are de-

voted to hepatics of the Gydan Peninsula and

adjacent territories (see Zhukova & Rebris-

taya 1987; Potemkin 1994). In the former,

there is an annotated list of 34 species, in-

cluding the only known in YG locality of

Radula prolifera. In the latter, 47 species

are reported from the southwestern part of

Gydan Peninsula. With respect to liverworts,

it appears that YG is now one of the best

studied areas of the Russian Arctic. Taking

into consideration the prevalence of lowlands

in this territory, it is likely that the 122 spe-

cies reported herein reflect the real richness

of the hepatic flora of this region. Only in

this region of the Russian Arctic has living

material been studied.

TAIMYR (TA). Data on liverworts of this

territory are scattered in many publications.

The first comprehensive contribution on the

hepatic flora of Lower Yenisey River was by

S. O. Lindberg & H. Arnell (1889). They re-

corded 51 species, including original descrip-

tions of Calycularia laxa and Jungermannia

(Mesoptychia) sahlbergii. Some species from

the coast of the Taimyr Peninsula are men-

tioned in “Die Moose der Vega-Expedition”

of H. Arnell (1917), and widespread north-

ern liverworts were reported by E. Ja. Zenko-

va (1953, 1954). In the 1970’s and 1980’s,

Zhukova published a number of papers on

Taimyr hepatics (see Zhukova, 1973a, 1974,

1977, 1979, 1981, 1986; Zhukova & Matveeva

1986), and she prepared a list of liverworts

of the Taimyr Peninsula that unfortunately

was not published, but was made available to

us. Some additional data were published by

L. S. Blagodatskikh & J. Duda (1982). At

present, 133 species are known from this re-

gion. It is apparent that the hepatic flora of

this area will continue to be augmented.

SEVERNAYA ZEMLYA (SZ). The only contri-

bution to the hepatic flora of Severnaya Zem-

lya Archipelago was recently published by

Potemkin (Andreev & al. 1993). Distribution,

ecology, and in some instances, peculiarities

of morphology, of 32 species and 7 infraspe-

cific taxa were presented in this paper. It is

certain that many additional species will be

found here in the future.

ANABAR-OLENEK AND KHARAULAKH REGIONS

(AO and KH). The description of the histo-

129

Liverworts of the Russian Arctic

ry of exploration of these two phytogeograph-

ical subprovinces is combined because explor-

ers usually collected liverworts on both the

right and left sides of the Lena River, which

is the border between AO and KH. A com-

prehensive treatment of liverworts (47 spe-

cies) of the Lower Lena River was published

by H. Arnell (1913). Later, Pseudolepicolea

fryei (Ladyzhenskaja 1963, 1964) and Anas-

trophyllum cavifolium (Zinovjeva 1969) were

added, and Z. N. Smirnova and A. E. Katenin

(1973) listed 15 species. In 1960, 1962, 1979,

and 1988, V. R. Filin collected hepatics on

the left and right banks of the Lena River,

and Konstantinova identified 78 species

among these collections (unpublished), includ-

ing 20 species new to arctic Yakutia (Repub-

lic of Sakha). At present, 96 species are known

from AO and KH. There can be no doubt

that the liverwort floras of both regions are

much richer than present documentation in-

dicates.

YANA-KOLYMA REGION (YK). This region

is the most poorly known with respect to he-

patics. Fifty-five species from Lower Indi-

girka River Basin were reported by O. M.

Afonina & J. Duda (1978), while 26 species

were recorded by N. A. Stepanova & J. Duda

(1984) from Lower Kolyma. At present, 53

species and 3 infraspecific taxa are document-

ed for this area. Without doubt the number

of liverworts known in this region will in-

crease more than two times in the future.

NOVOSIBIRSKIE ISLANDS (NS). The first list

of liverworts (32 species) of this subprovince

was published by B.N.Gorodkov (1956) for

Kotelny Island. Subsequently, 11 species were

reported by I. I. Abramov (1963) for the same

island, and identification of O. I. Sumina’s

collection by Zhukova added 11 species

(Zhukova & Sumina 1976). Zhukova (1982b)

published a list of 55 taxa for Bolshoy Lya-

khovsky Island, based on the collections of V.

D. Alexandrova. According to Zhukova

(1982b), the hepatic flora of NS is comprised

of 72 species, but some of these have been ex-

cluded in the course of our study, and pres-

ently 64 species are known for NS. Taking

into consideration the absence in the published

lists of widespread northern species as well

as the diversity of microhabitats it is evident

that much more species might be found there

in the future.

CHUKOTKA (including CC, SC, BC and WI).

Chukotka is divided herein into Continental,

Southern and Beringian Chukotka, and Wran-

gel Island. Up to the end of the 1960’s, only

20 liverwort species were known from Chukot-

ka as a whole (Abramova & al., 1985). De-

tailed investigations of the liverwort flora of

Chukotka were initiated in 1969 by Afonina,

who studied the mosses, but also collected

numerous hepatic specimens, which were iden-

tified by Duda. A detailed account of these

studies and annotated lists of species were

published by Afonina & Duda (1993). Some

specimens from Chukotka were revised by us,

which resulted in the addition of several new

species for this region (e. g., Cephaloziella

aspericaulis, Orthocaulis hyperboreus, etc.).

CONTINENTAL CHUKOTKA (CC) has been in-

sufficiently studied. Some data on the liver-

worts of CC were published in the first half

of the century (see Arnell, 1917; Gorodkov,

1939), and recently, Afonina & Duda (1992)

listed 69 species.

SOUTHERN CHUKOTKA (SC). Information on

the liverwort flora of this area can be found

in articles by Afonina & Duda (1983, 1987,

1989). A total of 121 species are presently

known from SC. Data on liverworts of this

region may be apparently enxpanded.

BERINGIAN CHUKOTKA (BC) is one of the

best known areas of the Russian Arctic with

respect to liverworts, and the data on the flora

are scattered in many publications, which are

summarized in Abramova & al. (1985). A to-

tal of 152 species are known from this region,

which has the richest flora in the Russian Arc-

tic. The richness of the flora can be explained

by the presence of mountains, a more-or-less

oceanic climate, the apparent absence of glaci-

ation; and relatively thorough exploration.

WRANGEL ISLAND (WI). The first data on

liverworts (26 species) of this region were pub-

lished by Gorodkov (1958). Zhukova (1978)

discovered Metacalypogeia schusterana and

Cryptocolea imbricata on this island, and she

later compiled an annotated list of 55 taxa

(see Zhukova 1987). A more comprehensive

list, which includes 86 species, was published

by Afonina & Duda (1988).

Liverworts of the Russian Arctic

COMMENTS

1. Anastrophyllum sphenoloboides is a rather poorly known

species that can be easily overlooked because of small size,

occurrence usually as a small admixture, superficial similarity

with Sphenolobus minutus.

2. Aneura pinguis var. denticulata was reported from Yamal

by Andrejeva (1981). We were unable to study this specimen.

3. The distribution of Anthelia julacea is based on litera-

ture reports; however, numerous specimens identified as A. ju-

lacea represent misidentified A. juratzkana f. elongata Joerg.

4. Barbilophozia rubescens is a poorly known taxon. This

large-celled liverwort was described recently from southern

Greenland by Schuster (1988), and he tentatively considered

it to be synonymous with a European endemic, B. hatcheri var.

grandiretis Lammes. In Greenland female plants were found ,

while in northern Europe (Murmansk Region, on islands of

Kandalaksha Bay of White Sea), only male plants are known.

The record of this species from ZF is based on revision of a

collection of Orthocaulis kunzeanus.

5. It is important to stress the necessity of identifying

Calypogeia collections when fresh because of the importance

of oil bodies for species determinations. The distribution listed

herein is based on literature records and studies of dried

material, so it may be not accurate.

6. The collection of Cephalozia bicuspidata var. lammersi-

ana from BC is sparse; therefore, it cannot be identified with

certainty.

7. The report of Cephalozia connivens from PU is based

on sterile material; however, the ecology is not characteristic

for C. connivens at the northern limit of its distribution, so we

believe this record is doubtful. The voucher specimen was not

available for us.

8. Old records of some species of Cephaloziella are unre-

liable because new species were described recently from the

Arctic and some specimens probably represent these taxa.

9. Cephaloziella arctogena surely is much more widespread

than our data indicate. When sterile, it is readily confused

with C. subdentata (Schuster, 1988; Potemkin, 1992). In the

last 5 years, C. arctogena has been found many times in the

Arctic (Potemkin, 1992; Konstantinova & Filin, unpublished),

as well as in southern Siberia (Konstantinova & Vasiljev,

1994) and Murmansk Region (Konstantinova, 1996).

10. Cephaloziella aspericaulis was identified from Chukot-

ka by Potemkin (see Konstantinova & al., 1992) and later was

found to be not very rare in this area.

11. According to Schljakov (1979), Cephaloziella divari-

cata is represented in Chukotka by the var. scabra only; how-

ever, the illustrations in his treatment resemble, in some re-

spects, C. aspericaulis. Reports of C. divaricata var. incurva

for ZF (Savicz, 1936), NS, WI (Gorodkov, 1956; 1958) should

be attributed to C. grimsulana s. l. (Schljakov, l.c.).

12. Cephaloziella divaricata var. ericetorum, C. hampeana

var. sibirica, C. rubella var. bifida are repoted by H.Arnell

(1917: 22-23). We were unable to study these specimens and

have no special opinion on these taxa.

13. The collections of Cephaloziella divaricata var. polystra-

tosa from ZF and NS are based on sparse sterile material and

should be considered tentative. Its taxonomic status, distri-

bution, and differentiation need to be reassessed.

14. All Yamal (YG) collections of Cephaloziella elegans

are based on sparse mostly sterile material and should be

considered tentative.

15. Cepaloziella hampeana was tentatively recorded from

NZ by S. Arnell (1947) (as C. cf. hampeana).

16. Cephaloziella subdentata was reported from NZ (Ar-

nell, 1947), but all the material seen by us belong to other

species of Cephaloziella (C. uncinata, C. arctogena).

17. We completely agree with Schuster (1980: 254, 256;

1988 : 229) that the “disposition of Arctic plants of Chiloscy-

phus remains problematical”. In many cases (especially in

dead material), it is very difficult to differentiate C. palle-

scens from C. polyanthos. Most arctic specimens were not

revised in the course of this study.

18. The report of Chiloscyphus pallescens from the Schokal-

sky Island (YG) by Zhukova & Rebristaya (1987) is based

on specimens of C. fragilis.

19. When sterile, Cladopodiella fluitans can easily be con-

fused with Gymnocolea inflata. For instance, in a specimen

from Dudinka (see Lindberg & Arnell, 1889, LE) determined

by H. Arnell as C. fluitans, only plants of Gymnocolea inflata

were found. Differentiation of these species is discussed in

detail by Schuster (1969: 792) and Schljakov (1979: 127).

20. The taxonomic status and distribution of Di plophyl-

lum taxifolium var. macrosticta are unclear to us.

21. According to Schuster (1995), Metacalypogeia (Hatt.)

H. Inoue subgenus Eocalypogeia (Schust.) Schust. should be

considered as a separate genus, Eocalypogeia (Schust.) Schust.

22. All reports of Frullania tamarisci from the Russian

Arctic are doubtful and more likely should be reffered to F.

nisquallensis (Schljakov, 1982; Schuster, 1992). Unfortunately

we were unable to study specimens from the Polar Urals and

Chukotka. The record of F. tamarisci from ZF (see Steere &

Inoue, 1978: 330; Schuster, 1992a: 51) reflects misinterpreta-

tion of the Russian text in Schljakov (1975).

23. Gymnocolea inflata var. acutiloba is very rare or ab-

sent in ZF. The collections from Rudolf Island could not be

found, and collections reported from elsewhere in ZF do not

belong to Gymnocolea.

24. Gymnomitrion apiculatum is probably more widespread

in the Russian Arctic, but it is often confused with other

species of the genus.

25. Gymnomitrion concinnatum is a highly polymorphic

species, and we believe that most varieties described, including

the var. ambigua Kaal. ex S. Arnell and the var. intermedium

Limpr., are not distinct.

26. According to Vana (1973: 278), specimens from Bulkur

and Kumachsur (Siberia, Lower Lena) determined as Aplozia

atrovirens (see Arnell 1913) should be referred to Junger-

mannia borealis. Also, it is likely that specimens from TA (see

Zhukova, 1973) and NS (see Gorodkov, 1956) represent Junger-

mannia borealis (cf. Damsholt & Vana 1977). Report of Aplo-

zia cordifolia (Hook.) Dum. var. sibirica H. Arnell & C. Jens.

from AO (H.Arnell, 1913:19) should be referred to Junger-

mannia eucordifolia Schljak. (J. Vana, pers. comm.).

27. Jungermannia polaris f. cavifolius (Schust.) Konst. &

Potemk. comb. nov. (basionym: Solenostoma polaris f. cavifo-

lius Schust. in Schust. & al., Natl. Mus. Canada Bull. 164:51,

1959) was found in ZF, YG, KH.

28. Only one specimen from ZF was identified as Leio-

colea cf. alpestris. Plants reported under L. alpestris by Zhuk-

ova (1973) represent atypical Lophozia major with sporadic

underleaves.

29. The junior author includes Lophozia confertifolia in

L. ventricosa (see Potemkin, 1994), but in the present treat-

ment, we follow Schljakov’s concept (see Konstantinova & al.,

1992: 121) and segregate it as a distinct species. Lophozia

groenlandica is a nomen rejiciendum. Lophozia confertifolia

evidently is much more widespread in the Arctic than our

140 N. A. KONSTANTINOVA & A. D. POTEMKIN

data indicate.

30. Lophozia excisa var. elegans was found by Schljakov

(1980) in specimens collected by Gorodkov on “one of the

Arctic islands”, and by Zhukova & Rebristaya (1987) from

Schokalsky Island, in the Kara Sea (YG). The latter specimen

(in LE) has been verified by us.

31. In spite of Schljakov’s (1979) decision to treat Lopho-

zia heteromorpha as synonymous with L. confertifolia (= L.

groenlandica (Nees) Macoun sensu Schljakov), we consider it

a distinct species.

32. Collections of Lophozia longidens from Yamal (YG)

are sparse and cannot be identified with certainty. Thus, the

occurrence of this species in this region needs to be verified.

33. Collection of Lophozia pellucida var. minor from SZ is

sparse and cannot be identified with certainty. Thus, the oc-

currence of this species in this region needs to be verified.

34. Collections of Lophozia rubrigemma from PU and

YG are sparse and cannot be identified with certainty. There-

fore, the records for these regions need to be verified.

35. The taxonomic status of Lophozia rufescens is un-

clear to us.

36. Lophozia savicziae can be easily recognized in the

field because of a very characteristic appearance, and under

the microscope, the oil bodies in fresh material are distinctive.

In contrast, the study of dry plants is often pointless. As noted

by Potemkin (1993), the taxonomic status of plants with bi-

concentric and granulate oil bodies (see also Schljakov 1973,

1980) is unclear. All localities of L. savicziae included in the

list should be considered tentative because they are based on

identification of dried material only.

37. All identifications of Lophozia schusteriana from the

Russian Arctic are based on dry plants (without oil bodies);

therefore, they are doubtful.

38. We agree with Schuster (1969: 613) that Lophozia

sudetica var. gelida is a xeromorphic phase of the species. Re-

ports of L. sudetica from Chukotka are based, partly, on mate-

rials of other Lophozia species, L. ventricosa s.l. particularly.

39. Differentiation of L. ventricosa s.str. and L. conferti-

folia in dried herbarium material, i.e. without oil bodies, is

troublesome. It seems that majority of records from the Rus-

sian Arctic should be referred to L. confertifolia (see Schlja-

kov, 1980).

40. According to Bischler-Causses’ and Boisselier-Dubay-

le’s (1991) lectotypification of Marchantia polymorpha, three

previously recognized species of the M. polymorpha-complex

roughly correspond to three subspecies of M. polymorpha.

Marchantia polymorpha corresponds to M. polymorpha ssp.

ruderalis Bisch. & Boisselier, M. aquatica to ssp. polymorpha,

and M. alpestris to ssp. montivagans Bisch. & Boisselier.

41. Marsupella aquatica has been revealed in collections

from Chukotka. The senior author consider this taxon a dis-

tinct species (see Schljakov, 1981; Frahm, 1993). In WI M.

aquatica f. pearsonii (Schiffn.) Schljak. was found.

42. Marsupella boeckii is often confused with Cephaloziella

species. In collections from Chukotka, it was found as an admix-

ture in many specimens of M. arctica and M. emarginata.

43. When sterile, Mesoptychia sahlbergii is subject for

confusion with the more widespread Leiocolea rutheana. The

differences between the two were discussed by Schuster (1969)

and Schljakov (1979).

44. Moerckia blyttii was reported from PU erroneously

by Zinovjeva (1973).

45. Nardia scalaris has a predominantly oceanic distribu-

tion, so the reports of this species from TA (Zhukova 1973b)

and PU (Zinovjeva, 1973) seem doubtful. Voucher specimens

were not available for us.

46. Obtusifolium obtusum was reported from ZF (see

Zhukova 1973a,c) erroneously.

47. All Polar Urals specimens refered to Orthocaulis at-

lanticus were found to be other species.

48. Most Russian Arctic specimens refered to Orthocaulis

attenuatus were found to be O. binsteadii.

49. Orthocaulis floerkei was found in one specimen from

ZF (the Rudolf Island) that was determined by Zhukova as

O. kunzeana.

50. Orthocaulis hyperboreus has been found in one speci-

men from Novaya Zemlya (Karmakulski, 13.9.1901 Ekstam,

UPS), which was determined by H. Buch as “species nova?”.

51. We cannot confirm the record of Orthocaulis kunzea-

nus from ZF; one of three available specimens represents an

impoverished transitional form between O. quadrilobus f. glar-

eosa and O. kunzeanus, while the rest represent other species.

In collections from YG three forms of Lophozia (Orthocau-

lis) kunzeana (f. acuta Schust., f. rotundiloba Schust. and f.

wenzellioides Schust.) were recorded (Potemkin, 1993).

52. Barbilophozia (Orthocaulis) quadriloba f. cephaloz-

ielloides (Schust.) Potemk. was recorded from YG by Potem-

kin (1993).

53. The distribution of Plagiochila arctica in the Russian

Arctic, as well as its differentiation from P. porelloides, need

to be assessed. In the Russian Arctic, these two species are not

demarcated so distinctly as Schuster (1980) suggested.

54. All examined specimens reported as Plagiochila arc-

tica from regions west of AO, except ZF, represent P. porel-

loides fo. subarctica (Joerg.) Konst. comb. nov. (basyonim:

Plagiochila asplenioides var. subarctica Joerg., Bergens

Mus. Skrifter 16:173, 1934). The latter taxon has been found

in ZF!, SZ!, AO!, CC, SC, BC.

55. We follow Schljakov’s (1981) concept and include Plec-

tocolea subelliptica (Lindb. ex Kaal.) Evans in P. obovata.

56. The distribution of Preissia quadrata ssp. hyperborea

in the Russian Arctic is unknown for the following reasons: 1)

this subspecies was recently described (Schuster, 1985, 1995);

2) many arctic collections are sterile; and 3) northward the

range of P. quadrata subsp. quadrata “remain undefined,

chiefly because the taxonomy of the species remains unclari-

fied” (Schuster, 1995: 370).

57. We agree with Schuster (1974) and Schljakov (1979)

that report of Protolophozia elongata from ZF (Ladyzhenskaja

& Zhukova, 1972b) is based on erroneous determinations, “judg-

ing from both text and figures of gemmiparous plants” (Schuster,

1974: 78). This specimen was not found in LE.

58. All reports of Riccardia spp. from the Russian Arctic

are based on materials without oil bodies and cannot be con-

sidered reliable (see Potemkin 1991).

59. In the Arctic, Riccia sorocarpa is apparently represent-

ed by the recently described ssp. arctica (see Schuster 1992,

Potemkin, 1993).

60. There are many misdeterminations of Scapania brev-

icaulis in materials from the Russian Arctic. The only verified

specimen of this species is from Continental Chukotka.

61. Specimens identified as Scapania calcicola from ZF

(see Zhukova, 1973b,c, LE) represent S. ligulifolia, S. zemliae,

and S. obcordata. Materials from TA and NS were unavail-

able for study.

62. Scapania gymnostomophila f. incurva (Bryhn & Kaal.

ex Bryhn) Schust. has been found by us in collections from

YG, TA, SZ, KH.

141

Liverworts of the Russian Arctic

63. The reports of Scapania kaurinii from NZ and YG

are based on sparse, sterile material and should be consid-

ered tentative.

64. Scapania lingulata is a variable species. Transitional

phenotypes between S. lingulata and S. microphylla occur, so

we consider these taxa as representing a single species. Zhuko-

va’s (1973b) report of S. lingulata from ZF is erroneous, but

S. Arnell (1947) correctly reported it from Novaya Zemlya

and Waygach Island.

65. The report of Scapania nemorea from ZF (Zhukova,

1973c) belongs to S. spitsbergensis (Potemkin, 1994). Also,

records of this species from Chukotka (Afonina & Duda, 1993)

and Lower Indigirka (Afonina & Duda, 1978) represent S.

nemorea subsp. crassiretis. Specimens from PU (Zinovjeva, 1973)

and NS (Zhukova, 1982) were unavailable for study. Appar-

ently, all reports of S. nemorea subsp. nemorea for the Arctic

are erroneous (see Schuster, 1974; Schljakov, 1981).

66. Scapania undulata f. aequatiformis De Not. has been

reported from PU (Novotny & Klimes, 1991).

67. All specimens of Schistochilopsis hyperarctica from

the territory of Russia that we examined are attributed to

other taxa, most often, to S. opacifolia. The only unrevised

record of this species for the Russian Arctic is Schljakov’s

(Schljakov, 1980 : 238-239), and this specimen unfortunately

was unavailable for study. The collection site, however, is atyp-

ical (peat hummock on brook bank, on peat) and distinctive

features mentioned by the author (bright green color and

larger gemmae) are not characteristic for S. hyperarctica. For

this reason, we consider this report doubtful too.

68. In spite of Schuster’s (1988) suggestion that Schis-

tochilopsis opacifolia should be included in S. incisa as a

subspecies,. We consicer it as a separate species.

69. Schistochilopsis incisa var. inermis (K. Muell.) Konst.

comb. nov. (basyonym: Lophozia incisa var. inermis K.

Muell., Leberm. in Rabenh. Kryptog.-Fl. 6, 1: 710. 1916).

According to Mueller’s original description this taxon differs

from the type variety in entire leaves, which are longer than

broad and bilobed to 1/2 their length, as well as in cells with

bulging trigones. Schljakov (1979:64), however, interprets the

var. inermis as mod. edentata (densifolia & laxifolia, leptoder-

ma & mesoderma) of S. incisa, which is fairly common in the

Arctic, and this may lead to erroneous reports of the variety. In

our opinion, the most distinctive character of S. incisa var. iner-

mis, associated with edentate leaves, is bulging trigones.

70. Solenostoma rubrum was reported from Chukotka by

Schljakov (in Konstantinova & al., 1992). However this spec-

imen is not available in LE.

71. Regional populations of Sphenolobus cavifolius differ

greatly (see Schuster, 1969; Zinovjeva, 1969; Schuster & Dam-

sholt, 1974; Schljakov, 1980), and this species often is a subject of

confusion with S. minutus, especially its “var. grandis” phases.

72. Sphenolobus minutus var. grandis is often confused

with S. cavifolius and also often has been not distinguished

from S. minutus var. minutum. Therefore distribution of these

taxa is known imperfectly.

73. Tetralophozia setiformis f. alpina (Hook.) Schljak. was

recorded from ZF.

74. The specimen of Tritomaria heterophylla from ZF is

poor, it cannot be identified with certainty. The f. anomala

Potemkin (see Potemkin, 1990b, 1993) was recorded from the

Yamal Peninsula.

75. Tritomaria quinquedentata f. gracilis Schust. has been

found in many regions (ZF!, NZ!, YG!, TA!, SZ!, AO).

76. Tritomaria quinquedentata var. grandiretis was re-

ported from Novaya Zemlya by Arnell (1947).

77. Jungermannia quinquedentata var. tenera H. Arnell &

C. Jens. was considered by Mueller (1951-1958) to be synon-

ymous with Tritomaria scitula. This lead to misinterpreta-

tion of the latter taxon and numerous erroneous reports of its

occurrence in the Russian Arctic. T. scitula was not found in

collections from ZF and NZ that were examined by us. We

accept the synonymizatoion of J. quinquedentata var. ten-

era with T. quinquedentata f. gracilis Schust. (Schuster,

1969).

ERRONEOUS AND DOUBTFUL RECORDS FROM

THE RUSSIAN ARCTIC

Blepharostoma arachnoideum M.A.Howe (Zinovjeva

(1973) is based on B. trichophyllum (L.) Dum. var. brevirete

Bryhn et Kaal.

Calypogeia azurea Stotler & Crotz (Afonina & Duda,

1993). A doubtful record from Chukotka. Identifications were

of plants without oil-bodies.

Calypogeia fissa (L.) Raddi (Zinovjeva, 1973). A doubt-

ful record from the Polar Urals.

Cephalozia affinis Lindb. ex Steph. (Zinovjeva, 1973). A

doubtful record from the Polar Urals.

Cephalozia lacinulata Jack ex Spruce (Zinovjeva, 1973;

Zhukova & Katenin, 1975, 1976) – There are doubtful records

from the Polar Urals and Chukotka Peninsula; and the record

from the vicinity of Vorkuta (Kildjushevsky, 1975) is based

on C. bicuspidata (Schljakov, 1979).

Cephaloziella biloba (Spruce) K.Muell. (Zhukova, 1973c,

1982b) is based on C. cf. divaricata var. polystratosa.

Cephalozilella dentata (Raddi) Migula (Zinovjeva, 1973)

is based on Cephaloziella cf. divaricata.

Cephaloziella elachista (Jack ex Gott. & Rabenh.) Schiffn.

(Zinovjeva, 1973) is based on Cephalozia bicuspidata (L.)

Dum.

Conocephalum japonicum (Thunb.) Grolle (Afonina &

Duda, 1993) is based on Marchantia sp. (very scant sterile

material).

Frullania jackii Gott. (Zinovjeva, 1973). A doubtful record

from the Polar Urals.

Geocalyx graveolens (Schrad.) Nees. Schljakov (1979b:

167) revised the specimens from Vorkuta (Kildjushevsky 1975)

as Lophozia collaris. The specimens from Chukotka (LE) iden-

tified by J. Duda as G. graveolens do not include this species.

Gymnomitrium crenulatum Gott. ex Carring. (Zinovjeva,

1973). A doubtful record from the Polar Urals.

Gymnomitrium obtusum Lindb. (Zhukova, 1973) = G.

coralliodes.

Harpanthus scutatus (F.Web. & Mohr) Spruce (Kildjus-

chevky, 1975). A doubtful record from the vicinity of Vorkuta.

Zinovjeva’s (1973) record of this species from Lagorta Pass,

Vaykar River bank, does not fall within the Arctic territory as

delimited herein.

Crossogyna autumnalis (DC.) Schljak. (Abramova & al.,

1974, 1985) is based on Plagiochila porelloides.

Jungermannia atrovirens Dum. (Arnell, 1913; Zhukova,

1973a; Gorodkov, 1956) is based on Jungermannia borealis

(see comment 26).

Jungermannia crenulata Smith var. gracillima (Smith)

Hook. (Zhukova, 1972) is based on Jungermannia polaris.

Jungermannia gracillima Sm. (Abramova & al., 1985) =

Solenostoma rubrum (Schljakov in Konstantinova & al., 1992).

Leiocolea gillmanii var. ciliolata Schust. (Zhukova 1973c).

142 N. A. KONSTANTINOVA & A. D. POTEMKIN

A specimen from Hooker Island (26.VII. 1930, V.P. Savicz)

represents Leiocolea cf. alpestris, whereas plants from Zemlya

Alexandry Island (8.VII.1959, V. D. Alexandrova) are attrib-

uted to Lophozia aff. excisa.

Lophocolea heterophylla (Schrad.) Dum. (Zinovjeva, 1973).

A doubtful record from the Polar Urals.

Lophozia ascendens (Warnst.) Schust. (Zhukova, 1982).

A doubtful record from Bolshoy Lyakhovsky Island (Novosi-

birskie Islands).

Lophozia excisa var. grandiretis S.Arnell (Zhukova 1973c)

is based on L. rubrigemma Schust. p.p. and Lophozia excisa

var. excisa. This is the only typical material of L. rubrigemma

from the Russian Arctic.

Lophozia uncinata Schljak. = L. excisa (Dicks.) Dum.

var. infuscata Schust. & Damsh. The type material was unavail-

able for study. Other specimens identified by one of au-

thors (ADP) are paroicous and represent Lophozia excisa

var. infuscata. Recently, Schljakov (pers. comm.) has indicat-

ed that he considers these two taxa synonymous.

Mylia verrucosa Lindb. (reports from Russian Arctic)

is based on M. taylorii (see Potemkin & Kazanovsky, 1993).

Odontoshcisma denudatum (Mart.) Dum.: all records of

this species from the Russian Arctic are erroneous, and repre-

sent either O. elongatum or O. macounii.

Odontoschisma sphagni (Dicks.) Dum. (Zinovjeva, 1973).

A doubtful record from the Polar Urals.

Scapania glaucocephala (Tayl.) Aust. (Zinovjeva, 1973).

A doubtful record from the Polar Urals.

Scapania umbrosa (Schrad.) Dum. (Arnell, 1947) from NZ

is based on S. scandica s.l. (20.VIII.1901 Ekstam, S!). The

record from the vicinity of Vorkuta (Kildjushevsky, 1975) is

doubtful.

Sphenolobopsis pearsonii Schust. & Kitag. (Zhukova, 1973b,

LE) is based on Sphenolobus minutus (Schreb.) Berggr.

Schistochilopsis laxa (Lindb.) Konst. (Zhukova, 1986) is

based on L. incisa.

Tritomaria quinquedentata var. turgida is based on T.

quinquedentata var. quinquedentata (Potemkin, 1993: 80).

Vegetation of the southern part of Bolshevik Island (Severnaya Zemlya Archipelago)

Article

Jan 2006

Nadya Matveyeva

Bolshevik Isl. is the one of the largest islands within the Severnaya Zemlya archipelago. It is situated in the southern part of the polar desert zone. In the course of three field work trips in 1997, 1998 and 2000 years 252 relevees were made in its southern part on three geomorphologic surfaces: coastal plain, inner upland close to glacier and ancient high river terraces. As the result 27 syntaxonomical units of different rank (15 associations, 2 subassociations, 2 variants, and 8 community types) were described using Braun-Blanquet approach. All syntaxa, except one, are new and mostly similar to communities described on Franz Josef Land. The problems were to put new syntaxa into the higher level units (including class) within the syntaxonomical hierarchy. The main bulk of syntaxa, both zonal and intrazonal ones, has to be preliminary placed into Salicetea herbaceae class although there is a lot of reasons to consider zonal syntaxa as a new class that is specific for the polar desert zone. In any case, there are no one syntaxon that can be referred to Loiseleurio-Vaccinietea class that combines zonal vegetation in the tundra zone. The wide ecological range of great majority of species as well as the changes of their intralandscape distribution compare to the tundra zone made additional difficulties in finding character and differential species. 340 species (vascular plants — 52, mosses — 97, liverworts — 41, lichens — 150), that compiles 73 % of the whole island flora and 84 % of its southern part, were recorded within the all relevees. Almost half of these (182) are very rare on the island and 127 species were met 1—2 times. There are 70 species with wide ecological range throughout all landscape types with such commonly distributed herbs as Saxifraga cernua, S. hyperborea and Stellaria edwardsii, mosses Polytrichastrum alpinum and Sanionia uncinata and lichen Stereocaulon rivulorum among these. Phippsia algida, the character species for snow bed communities, occurs in about 70 % of syntaxa. Useful for differentiation of syntaxa have been appeared 87 species. Few species with wide distribution within a landscape demonstrate their preference to a certain syntaxon by higher abundance (preferential character species). These are mostly bryophytes: mosses Bryum cryophilum and Grimmia torquata, and liverworts Gymnomitrion corallioides, Marsupella arctica and Scapania crassiretis. Cryptogam species predominate in the whole flora as well as in each syntaxon. The number of species varies from 12 to 70 per sample plots 5÷5 m and from 20 to 195 in different syntaxa. The richest in species (70 per community and about 190 for association) are zonal plant communities on the accumulative coastal plain in the region of Solnechnaya Bay, the poorest one, with 10 and 20 species consequently, is ass. Hygrohypno polari—Saxifragetosum hyperboreae that was described on the upland, close to glacier in the inner part of island.

Nov 2021

The paper provides the data on mosses and liverworts of the Stolbovoy Island, situated in the New Siberian Islands of the Arctic Ocean, on the far north of the Republic of Sakha (Yakutia). The annotated list includes 140 species of mosses and 58 species of liverworts. For every species, data on localities, frequency, habitats are provided. For the first time, 119 species of mosses and 54 species of liverworts were revealed for Stolbovoy Island, and 40 species of mosses and 22 species, 5 varieties, and 2 forms of liverworts for the New Siberian Islands. Schistidium grandirete, Cephalozia hamatiloba, Lophozia cf. svalbardensis, Scapania cf. ligulifolia are reported for the first time for Yakutia. Bryo erythrophyllum rubrum, Rhizomnium gracile, Sphagnum concinnum were revealed for the first time for Yakutia in our collections from Stolbovoy Island but published earlier. A new combination for Pseudotritomaria heterophylla f. anomala is published.

Ultraviolet radiation–protecting pigments in plants growing at Arctic region

Chapter

Jan 2021

The most apparent characteristic of the Arctic climate is that it is not only cold but dry also. The Arctic ecosystem is extensive but poorly understood due to limited scientific investigations because of logistic requirements. Due to depletion of ozone concentration, higher ultraviolet-B (UV-B) radiation reaches Earth’s surfaces, especially at Poles. The higher amount of UV-B radiation causes adverse effects on floral components of the Arctic region. The Arctic ecosystem is dominated by vascular plants, bryophytes, lichens, and algae. Most Arctic plants produce UV protective pigments in response to UV-B radiation to cope with UV-B radiation's adverse effects. Different taxa synthesize unique types of UV-absorbing substances/pigments. For example, cyanobacteria synthesize scytonemin and mycosporine-like amino acids; lichens parietin, perlatolic acid, fumarphotocetraric acid, and usnic acid; and mosses neoxanthin, violaxanthin, lutein, epoxide, anteraxanthin, zeaxanthin flavones, and flavonol glycosides. UV-absorbing substances and phenolics are the important pigments synthesized by the Arctic plants under UV radiation. In almost all the Arctic plants, it has been found that induction of UV-absorbing pigments/substances takes place when exposed to high UV radiation, but there are some exceptions also. UV-B protecting pigments are useful in screening out the harmful UV-B radiation and protecting the plants. It is among the essential mechanisms of survival in plants during the ozone-depletion period of Arctic spring and summer. Studies related to enhanced solar UV radiation show an increase in the concentration of greenhouse gases, and climate change needs realistic assessment of Arctic’s flora of pristine environment so that an understanding can be developed on the survival and conservation of Arctic ecosystem.
