Ornithogalum L. is widely distributed in Europe, Asia
(reaching Afghanistan to the East), Africa (except the
Tropic of Cancer) and Madagascar (Zahariadi 1965). The
number of species included in Ornithogalum
, and hence
its circumscription, has been a matter of controversy.
In a traditional sense, it includes about 120–130 taxa
m 1989), or even 200–250 according to Obermeyer
(1978) and Mu
ller-Doblies and Mu
ller-Doblies (1996). On
the basis of floral and reproductive characters, many sections
(Engler 1888; Zahariadi 1965, 1977) and subgenera (cf.
Baker 1872; Zahariadi 1965, 1977, 1980; Obermeyer 1978)
have been accepted within Ornithogalum, many of them
based on previously described genera (cf. Gray 1821;
Rafinesque 1837; Parlatore 1854; Salisbury 1866).
In recent times, very different arrangements, almost
opposite to one another, have been proposed. On the one
hand, Speta (1998) circumscribed Ornithogalum to the
Eurasian and North African taxa of O. subg. Ornithogalum
(=O. subg. Heliocharmos Baker), which was hence con-
formed by 50–60 species, and he regarded the rest of the
groups as autonomous genera such as Albuca L., Cathissa
Salisb., Coilonox Raf., Dipcadi Medik., Eliokarmos Raf.,
Honorius S.F. Gray, Loncomelos Raf., Melomphis Raf.,
Neopatersonia Scho
nland, Pseudogaltonia Kuntze, Stella-
rioides Medik. and Zahariadia Speta. On the other, Manning
et al. (2004) reduced all these genera to Ornithogalum,
which resulted in over 300 species and was thus coincident
with subfamily Ornithogaloideae
. Finally, Manning et al.
(2009) reconsidered the taxonomic identity of taxa within

this subfamily and recognized only four genera: Ornitho-
galum, Albuca, Dipcadi and Pseudogaltonia.
However, phylogenetic studies we are undertaking in the
Ornithogaloideae, based on sequencing of plastid (trnL-F,
rbcL and matK) and nuclear (ITS) regions combined with
morphological data (Martı
n et al. 2010b) indicate
the monophyly of O. subg. Ornithogalum, as well as of
other related subgenera. Due to this fact, a narrower cir-
cumscription of Ornithogalum can also be assumed in
which up to 19 genera are accepted, being well charac-
terized morphologically, phylogenetically and biogeo-
graphically. In the present study O. subg. Ornithogalum is
circumscribed in the sense of O. subg. Heliocharmos
(Baker 1872), and corresponds fully to Ornithogalum sensu
stricto (cf. Speta 1998; Martı
n et al. 2010b).
Ornithogalum subg. Ornithogalum includes plants with:
inflorescences wide and short corymbose or pseudocorym-
bose; floral and fruiting pedicels erect-patent to reflexed;
tepals white on the adaxial face bearing a central green band
on the abaxial face; filaments linear or tapering contracted
abruptly at their apexes; ovary oblong, ovoid or obovoid,
truncate at the apex with six evident ribs in section; long and
filiform style and small trigonous stigma; and seeds globose
with reticulate testa (Moret et al. 1990). About 50 species
are usually included in this group (cf. Speta 1998; Martı
n et al. 2010b), which are distributed mainly in the
Mediterranean basin, but reaching the Middle East.
Many taxa have been described in O. subg. Ornithogalum
on the basis of subtle morphological variations, usually with
little biological significance (Moret and Galland 1992).
Following Landstro
m(1989), more than 150 taxa were
described in O. subg. Ornithogalum from the Mediterranean
and Irano-Turanian regions, but only 20 or 30 species could
be accepted, and he emphasized the need for a global revi-
sion in the whole subgenus. This complex taxonomy can be
due to intraspecific variation, the plasticity of individuals,
their habit strongly dependent on the environment and poor
conservation of the types (Moret and Galland 1992). Fur-
thermore, the original concepts of taxa were usually modi-
fied by later authors, who made very different links among
taxa on the basis of very different criteria. All these factors
led to a wide diversity of taxa conceptions, and generated an
extremely confusing taxonomy (Peruzzi et al. 2007). The
description by Greuter (1988)ofOrnithogalum as ‘being an
execrable genus’ can be perfectly applied to the current
understanding of most taxonomists about this genus.
Brief history of O. subg. Ornithogalum in the Iberian
Peninsula and the Balearic Islands
The taxonomy of the species included in O. subg. Orni-
thogalum in the Iberian Peninsula and the Balearic Islands
is very diverse and confusing. During the last 250 years, up
to 11 species (O. algeriense Jord. & Fourr., O. baeticum
Boiss., O. bourgaeanum Jord. & Fourr., O. collinum Guss.,
O. divergens Boreau, O. exscapum Ten., O. kochii Parl., O.
monticolum Jord. & Fourr., O. orthophyllum Ten., O. ten-
uifolium Guss. and O. umbellatum L.) have been cited for
the Iberian and Balearic floras (Boissier 1838; Lange 1860;
Willkomm 1862; Jordan and Fourreau 1866; del Amo y
Mora 1871; Ruiz-Rejo
n 1978; Colmeiro 1889; Willkomm
1893; Zahariadi 1980; van Raamsdonk 1984, 1985a, b,
1986; van Raamsdonk and Heringa 1987; Moret et al.
1987; Pastor 1987; Moret and Galland 1992; Franco and
Rocha Afonso 1994; Devesa 1995; Aizpuru et al. 2000
s and Vigo 2001), most of them being described from
France, Italy or Algeria (cf. Linnaeus 1753; Tenore 1811,
1829, 1830; Gussone 1825, 1827; Boreau 1847; Parlatore
1857; Jordan and Fourreau 1866), but their relationships
with the Iberian and Balearic plants have never been
shown. As an exception, Boissier (1838) described
O. baeticum from the summits of S
Bermeja, near
Estepona (Ma
laga, southern Spain), a taxon that he related
to O. umbellatum and O. exscapum Ten. Both latter species
were later cited by Lange (1860). First, he mentioned
O. umbellatum from central and southern Spain, whereas
O. exscapum was restricted to Sacromonte in Granada, a
locality that was recorded by several authors (Willkomm
1862; del Amo y Mora 1871; Colmeiro 1889). Lange
(1860) also noted that some young exemplars collected
near Co
rdoba were akin to O. comosum L., because of their
very long, acuminate floral bracts.
Willkomm (1862) reported O. umbellatum, a plant
whose type locality is Blois (France) (cf. Stearn 1983), as
widespread in most of the eastern half of Spain. He
accepted two varieties differing in capsule shape and length
of the floral bracts: (1) var. genuinum Willk. from Castilla,
n and Catalun
a; and (2) var. longebracteatum Willk.
(incl. O. baeticum) from Granada, Ma
laga and Ca
diz, in
which he segregated a form named nevadense Willk. (as
‘‘ Nevadensis’). Both taxa were revisited by Pau (1922),
who accepted O. umbellatum with two additional varieties:
(1) var. baeticum (Boiss.) Pau from S
Bermeja, which he
considered synonymous with O. umbellatum var. longe-
bracteatum Willk., and (2) var. nevadense (Willk.) Pau
from Cerro Lucero in Co
mpeta (Ma
laga). Moreover,
Willkomm (1862) also suggested the strong possibility of
both O. divergens and O. tenuifolium being found in
a and Valencia. In fact, the former was reported by
Pau (1888) from Segorbe (Castello
n), and later Willkomm
himself (1893) and Colmeiro (1889) added some localities
for both taxa from several sites in northeastern Spain.
The last taxon of this subgenus to be described from the
Iberian Peninsula was O. bourgaeanum (Jordan and Four-
reau 1866), with its type locality near Plasencia, Ca

(western Spain). It has been almost overlooked until today,
being implicitly included in the traditional concept of
O. orthophyllum subsp. baeticum (Boiss.) Zahar. (cf.
Devesa 1995).
In recent times, Zahariadi (1980) accepted five taxa for
the Iberian Peninsula (O. collinum, O. exscapum, O. um-
bellatum, O. orthophyllum subsp. baeticum and O. diver-
gens), to which Moret and Galland (1992) later added
O. algeriense. However, according to most recent authors
(Tutin et al. 1980; Devesa 1995; Valde
s et al. 1987;
Aizpuru et al. 2000; Bolo
s and Vigo 2001), traditionally at
least two taxa of O. subg. Ornithogalum have been
accepted in the Iberian Peninsula and the Balearic Islands:
O. umbellatum and O. orthophyllum subsp. baeticum. They
were differentiated mostly by the disposition of the capsule
ribs and number of bulbils (equidistant and numerous in the
former, paired and absent in the latter).
As a result of the scenario discussed above, identifi-
cation of Iberian and Balearic individuals of Ornitho-
galum subg. Ornithogalum is extremely difficult. This is
due to different factors: (1) their wide morphological
plasticity produces the overlapping of most of the mor-
phological characters used in the available identification
keys (e.g. the relative length of the bracts with regard to
their pedicels); and (2) species mostly accepted for the
Iberian and Balearic territories (O. orthophyllum and
O. umbellatum) were described from Italy and France,
respectively, and their identity has never been confirmed
by detailed comparison with plants from the type locali-
ties. On this matter, Gadella (1972), Gadella and van
Raamsdonk (1981), van Raamsdonk (1986), Moret
(1992), and Moret and Galland (1992) found evidence
that O. umbellatum corresponds to the triploid plants with
medium sized secondary bulbils which bear leaves in the
first year, and have not reached the Iberian Peninsula.
Similarly, Garbari et al. (2003, 2008), after comparing
populations from the classic locality of O. orthophyllum
sensu stricto in central Italy, concluded that this taxon is a
diploid species endemic to the Abruzzi mountains. On the
other hand, the existence of Iberian populations of
O. monticolum and O. algeriense has been demonstrated
on a solid cytological and morphological basis (van
Raamsdonk 1986; Moret and Galland 1992; Bolo
s and
Vigo 2001; Bolo
s et al. 2005).
Data are presented here for a revision of O. subg.
Ornithogalum in the Iberian Peninsula and the Balearic
Islands, as a part of a global study on the genus that is
being carried out (cf. Martı
n et al. 2007a, 2009,
2010a, b). The morphological data shown here are conso-
nant with a genetic study of the group using the AFLP
technique (Martı
n et al. 2007b; Mar
et al., unpublished data), which strongly supports the tax-
onomy adopted here.
Materials and methods
In this study, a review of a total of 901 vouchers conserved
at the herbaria ABH, BIO, BC, BCN, COI, GDA-GDCA,
SALA, SANT, SEV and VAL (acronyms following Thiers
2010) was undertaken.
As some of the herbarium materials were not complete,
fragments on vouchers were commonly found to be prob-
lematic, since some important structures were lacking (e.g.
bulbs, fruits, or seeds, among others), or measuring certain
structures (e.g. dimensions of the filaments of the stamens
or ovary) would involve serious damage to the material.
Therefore, morphological studies have usually been
undertaken on living material from natural populations, and
within a few hours of collection. A total of 339 fresh plants
from several populations were studied in order to achieve
the maximum morphological variation of each taxon. For
O. bourgaeanum, 235 specimens from 28 populations were
studied, for O. baeticum 46 specimens from 8 populations,
and for O. divergens 24 plants from 5 populations
(Table 1). Additionally, 13 individuals from three French
populations of O. monticolum and 21 individuals from
three Moroccan sites of O. algeriense were also included.
Morphological studies were based on comparison of
both qualitative and quantitative features of bulbs, leaves,
flowers, fruits and seeds, as described in detail by Martı
n et al. (2007a, 2010b), as well as on other fea-
tures related to both scanning electron microscopy
techniques and fresh plant scanning. Moreover, the fol-
lowing new characters were also considered:
Number and type of bulbils: The number of bulbils was
counted in each individual when they were present. Fur-
thermore, the type of bulbils was considered, differentiat-
ing between secondary bulbils, usually small and
pediculate, and sessile and larger bulbils generated by
division of the mother bulb into portions of similar size
which shared the basal plate.
White band width: The maximum width of the central
white band of the leaf was measured, and values are
expressed in millimetres.
Morphology of the capsule section: The capsules were cut
transversally and their morphology and rib structures were

Among all of the characters, only 39 quantitative char-
acters (Table 2) were used for the statistical tests. An initial
principal component analysis (PCA) was conducted
including all measured quantitative characters to explore
morphological variation within the five considered taxa of
O. subg. Ornithogalum: O. algeriense, O. baeticum, O.
bourgaeanum, O. divergens and O. monticolum. Later, a
second PCA was done according to the highest values of
the previous variance obtained from the first and second
principal components, which therefore would assess the
main statistical support among the taxonomic identities. A
discriminant analysis was also performed to check the fit-
ness of the latter PCA results. To identify those features
that had the highest potential as diagnostic characters, we
submitted the dataset to a stepwise discriminant analysis.
The value of the inclusion criterion was set at F = 3.84
and the exclusion criterion at F = 2.71 (default values in
SPSS). A classificatory discriminant analysis was per-
formed with the characters that were included in the step-
wise discriminant analysis. The morphological distinction
among taxa was determined by studying the frequency
distribution of the discriminant scores, and the classifica-
tion was evaluated by cross-validation. All analyses were
conducted with the software SSPS v. 14.
Plant names and authorities are in accordance with the
International Plant Names Index (IPNI 2010). Dots on the
distribution maps correspond to both herbarium material
and studied living populations. For each taxon, only a
selection of localities are listed to avoid repetition and to
shorten information.
Statistical analyses
In the initial PCA of all 39 studied quantitative morpho-
logical characters, nine principal components were
obtained, which explained together 75.6% of the variance,
the two first components being responsible of 42.7% of the
variance (31.8% and 10.9%, respectively). All five taxa
considered in the subgenus appeared rather mixed (Fig. 1).
However, a clear gradient was observed along the first axis
after delimiting three groups: O. bourgaeanum (plus
O. monticolum), O. baeticum (plus O. algeriense) and
O. divergens. All three biological entities showed a wide
overlap of many morphological characters, some of which
were rather discriminative concerning secondary bulbils,
inflorescence and flower features (Table 2). The second
principal component was not effective in distinguishing
taxa. In fact, the values obtained and percentages of vari-
ance explained were very low in all cases.
When only characters with the highest values were
selected (Table 2), a clear differentiation of three groups
was again shown in the subsequent PCA (not shown) and
discriminant analysis (Fig. 2). Accordingly, only three
species are hereafter accepted as O. bourgaeanum (incl.
O. monticolum), O. baeticum (incl. O. algeriense) and

O. divergens. The results of both tests were fully congru-
ent, although the discriminant analysis produced a clearer
segregation (Fig. 2). Cross-validated classification results
of this discriminant analysis showed that more than 95% of
the specimens that were assigned a priori to the three
groups were classified correctly. Four functions were
obtained: the first canonical axis explained 54% of the
variance and was based mainly on the number of bulbils,
and the second one explained the remaining 38.7% of the
variance and was related basically to the style length
(Table 3).

Bulb sizes were similar in the three considered taxa. The
bulb of O. bourgaeanum (incl. O. monticolum) showed the
largest and smallest values, whereas O. baeticum (incl.
O. algeriense) and O. divergens usually showed middle
sizes (Table 4). Regarding the shape of the bulb, O. bae-
ticum and O. bourgaeanum produced ovate bulbs, whereas
the bulb in O. divergens was usually slightly depressed.
The number, size and shape of the bulbils were also sig-
nificant features. O. divergens showed several small,
spherical and pediculate secondary bulbils (Table 4),
whereas the other ones did not show these features, though
they produced the largest and sessile primary bulbils gen-
erated by the division of the mother bulb, sharing its basal
plate. Finally, bulb scales were almost completely conc-
rescent in O. divergens, whereas they were free and
imbricate in O. bourgaeanum and O. baeticum.
The number, size and morphology of the leaves were quite
similar among the three studied taxa. The number of leaves
usually varied from four to eight, although in O. bour-
gaeanum (incl. O. monticolum) the number reached 12
(Table 4). The longest and widest leaves were again seen in
O. bourgaeanum, although the usual values were quite
similar with much overlap in the three taxa (Table 4).
Moreover, all three taxa showed a central white band on
the adaxial side of the leaves which was due to an inter-
ruption in the palisade tissue in the central portion of the
leaf (cf. Peruzzi et al. 2007). In the studied taxa, the white
band was very variable in width, although some individuals
of O. baeticum (incl. O. algeriense) showed the widest
white bands (Table 4). Finally, leaves of O. baeticum were
glaucous green, at least when sprouting, whereas the other
taxa had bright green leaves.
Species of O. subg. Ornithogalum produced inflorescences of
similar length and width, usually corymbose or pseudoc-
orymbose-racemose, with the lowermost pedicels much
longer than the upper ones. The size and shape of the inflo-
rescences, as well as the floral pedicel length were extremely
variable (Table 4). However, the relative disposition of the
lowermost pedicels yielded differences among the studied
taxa. O. bourgaeanum (incl. O. monticolum)andO. baeticum
(incl. O. algeriense) had erect to erect-patent pedicels,whereas
O. divergens showed very long and patent or slightly deflexed
lowermost pedicels, showing clear differences in relation to
the other species. Regarding the bracts, their absolute length
and width were very similar in the three considered taxa, with
much overlap. Floral bracts of O. bourgaeanum and O. bae-
ticum were usually either a bit shorter than the pedicels or a bit
longer, and exceptionally were much shorter and even up to
half of the pedicel length. On the contrary, at least the lower-
most bracts of O. divergens were constantly much shorter than
their pedicels, around half of their length.
The length and width of the tepals and their shape in the
three considered taxa were extremely variable. Tepals
varied from acute to obtuse, even in the same population.
Moreover, their size could vary strongly even in a single
individual, when considering mature flowers of the lower
part of the inflorescence or the younger ones from the
upper part. The largest values of tepals was seen in O.
divergens (Table 4), although it produced a lower number
of flowers per inflorescence (Table 4). On the contrary, O.
bourgaeanum (incl. O. monticolum) showed the smallest
tepals (Table 4), although again it generates the highest
number of flowers per inflorescence (Table 4). O. baeticum
(incl. O. algeriense) usually shows intermediate values.

Finally, the width of the dorsal green band of the tepals
was also variable with much overlap among the taxa. The
outer tepals usually showed wider green bands than the
inner tepals. In O. divergens, the band usually reached
7 mm, whereas in the other taxa it did not usually exceed
5 mm (Table 4).
The stamen laments of both whorls were lanceolate to
tapering and abruptly contracted at the apex. The inner fila-
ments were slightly broader and longer than the outer fila-
ments, which embrace the septal nectaries of the ovary,

gathering the nectar and offering it to the insects. The three
studied taxa showed very similar filaments. However, the
filaments were widest in O. divergensand were a bit smaller in
the other two taxa with much overlap among them (Table 4).
The ovary was very similar in all studied taxa, being obo-
vate to oblong, truncate at the apex and showing six distinct
ribs in section. However, O. divergens showed the longest
ovary, O. bourgaeanum (incl. O. monticolum) the shortest
ovary, and O. baeticum (incl. O. algeriense) an ovary
intermediate in length (Table 4). O. bourgaeanum showed
the narrowest ovary, and O. baeticum and O. divergens
showed the widest ovary (Table 4). However, there was
great overlap among the studied taxa for all these characters
(Table 4). On the contrary, the absolute length of the style
was a crucial and easy character to differentiate these
taxa, as supported by the discriminant analysis (Table 3).
O. divergens and O. bourgaeanum showed a similar style
length (up to 3.8 (4) mm), whereas in O. baeticum the style
length was usually 4 mm or more (Table 4).
Fruit and seeds
The size and morphology of the capsule allowed the species
to be differentiated. The capsules of all the studied species
were oblong, ovate or obovate, and truncate at the apex
(Figs. 3, 4 and 5; Table 4). Nonetheless, in O. baeticum (incl.
O. algeriense) the capsules were mostly oblong with a length
up to twice the width, whereas in O. bourgaeanum (incl.
O. monticolum) (Fig. 4) and O. divergens (Fig. 5) the cap-
sules were usually ovate or obovate with a length a little more
than or the same as the width. On the other hand, the mor-
phology seen in transverse sections of the capsules showed
interesting differences. In O. baeticum all furrows were
similar, flattened or obtuse, giving a trigonous or polygonal
appearance in section (Fig. 3). However, in O. bourgaeanum
the furrows on the suture of the carpels, coinciding with the
septal nectaries, were deep and wide or obtuse, whereas the
furrows on the midveins of the carpels were much narrower
and acute, giving a paired aspect to the ribs (Fig. 4). Finally,
in O. divergens the capsules had six evident and more or less
equidistant ribs with deep furrows (Fig. 5).
Seeds of the studied taxa were globose and slightly
apiculate (Fig. 6), with the seed testa reticulate. First, O.
baeticum (incl. O. algeriense) showed very prominent ret-
icules, in which the cellular walls could easily be identified
(Fig. 6). Moreover, they were clearly apiculate, or they
could show a distinctive crest from the apex to the opposite
pole. On the other hand, the seeds of O. bourgaeanum (incl.
O. monticolum) and O. divergens (Fig. 6) were globose and
scarcely apiculate and their testa showed less prominent
reticules with the cellular walls not so evident. Regarding
the size of the seeds, O. baeticum showed the largest seeds,
whereas O. bourgaeanum and O. divergens had smaller
seeds with a wide overlap between them (Table 4). Seed
weight was an overlapping character, since O. bourgaea-
num showed the highest and the lowest seed weights, and
both the other species showed medium values (Table 4).
Thus, O. baeticum and O. bourgaeanum showed the highest
number of seeds per capsule, whereas O. divergens showed
the lowest (Table 4). However, there was great overlap in
all these characters. Regarding seed colour, O. baeticum
had bright blackish seeds, whereas O. bourgaeanum and
O. divergens had caramel brownish or dull blackish seeds.
After the morphological studies and the statistical analy-
ses, only three biological entities—O. bourgaeanum,

O. baeticum and O. divergens—were accepted in O. subg.
Ornithogalum in the Iberian Peninsula and the Balearic
Islands. They showed different morphological traits and
particular ecological behaviours. Both O. monticolum and
O. algeriense were indistinguishable from O. bourgaeanum
and O. baeticum, respectively, and hence they are here
included in their synonymy. Combining all morphological
characters yielded poor complete segregation of these taxa,
as shown by the total PCA analysis (Fig. 1), due to their
wide morphological plasticity, and overlap in most of their
vegetative and reproductive characters. This could explain
the confusing taxonomy adopted in this subgenus over
recent centuries. However, among all the studied charac-
ters, some certain vegetative and reproductive features
were revealed as diagnostic for the identification of the
three taxa, as deduced from the values obtained in the
discriminant analysis (Table 3; Fig. 2), and they are dis-
cussed below.
With regard to bulbs, the number and type of bulbils
allowed easy differentiation between O. divergens and both
O. bourgaeanum and O. baeticum. The presence of bulbils
has commonly been used by authors dealing with the
Iberian and Balearic taxa (cf. Coutinho 1913, 1939;
Zahariadi 1980; Pastor 1987; Devesa 1995; Aizpuru et al.
2000; Bolo
s and Vigo 2001) as a diagnostic character in
O. subg. Ornithogalum. They characterized O. divergens
(mostly referred as O. umbellatum’) as bearing bulbs with
numerous bulbils, and O. bourgaeanum and O. baeticum
(usually merged under O. orthophyllum subsp. baeticum’)
as bearing bulbs lacking or with very few bulbils. How-
ever, there are important differences not only in the number
of bulbils but in their type, as discussed by Landstro
(1989) and Moret (1991). On the one hand, O. divergens
produces many (up to 41) secondary bulbils, called ‘bul-
bils’ by Landstro
m(1989) and ‘bulbilles’ by Moret (1991),
which mostly lack leaves and rest for one or more years
before sprouting and becoming mature plants. They are
solid with a firm external coat, very small (5–8 mm in
diameter), spherical and pediculate, and do not share the
basal plate with the mother bulb, being generated under its
outer tunic. This type of bulbil is found only in polyploid
taxa (cf. Landstro
m 1989). On the other hand, both
O. bourgaeanum and O. baeticum can generate primary
bulbils by splitting of the mother bulb into two or more
identical parts, which were therefore called ‘sister bulbs’
by Landstro
m(1989), and which can sprout and bloom just
from the next year (cf. Moret 1991). These sister bulbs

appear in low numbers, are sessile, large, and share the
basal plate and the outer tunics with the mother bulb. This
second type is more commonly found in the diploid taxa of
the subgenus (cf. Landstro
m 1989).
A third type of bulbil is found in the subgenus, which
includes few, leafy and medium-sized secondary bulbils,
external to the outer tunic of the mother bulb. They were
named ‘caı
eux’ by Moret (1991) or ‘side bulbs’ by Lands-
m(1989), and can be observed in the type (iconotype)
O. umbellatum s.s. (cf. Stearn 1983). As we have not found
any Iberian or Balearic plant matching these types of sec-
ondary bulbils, according to van Raamsdonk (1986)we
excluded the presence of O. umbellatum in both territories.
Summarizing, the depressed bulb shape and concrescence of
the bulb scales in O. divergens (cf. Speta 2000), together with
the number and mainly the type of bulbils, are shown here
to be crucial characters for segregating that taxon from
O. bourgaeanum and O. baeticum (Fig. 2; Tables 3 and 4).
Moreover, in both latter species bulb scales were free and
imbricate, allowing easy distinction from O. kochii, in which
they are completely concrescent (cf. Garbari et al. 2008).
Morphology and the size of leaves have also been used
for taxonomy of O. subg. Ornithogalum (cf. Zahariadi
1980; Pastor 1987; Devesa 1995; Franco and Rocha
Afonso 1994). Similarly, Bolo
s and Vigo (2001) have
argued that the existence of a marked central white band on
the adaxial side of the leaf allow the differentiation of
O. divergens (as ‘O. umbellatum subsp. umbellatum’) from
both O. bourgaeanum (as O. umbellatum subsp. monti-
colum’) and O. baeticum (as O. umbellatum subsp. bae-
ticum’), in which it was weakly visible. However, our
studies on the Iberian and Balearic plants show extreme
variability in the length and width of the leaves, as well as
in the features of the central band that is present in all
individuals, with a wide overlap among the three accepted
taxa (Table 4
). Conversely, the colour of the young leaves
can be used to differentiate O. baeticum (with glaucous
leaves) from O. bourgaeanum and O. divergens (both with
bright green leaves), as pointed out by Moret and Galland
(1992). Therefore, on the basis of leaf characters, O. exs-
capum, a plant described from Naples (Italy) and distrib-
uted throughout the central and eastern Mediterranean (cf.

m 1989; Garbari et al. 2008), should be excluded
from the Iberian and Balearic floras since its leaves do not
show such a white band (cf. Tenore 1811). All references
to its presence in Sacromonte, Granada (Lange 1860;
Willkomm 1862; del Amo y Mora 1871; Colmeiro 1889)
surely correspond to young, immature forms of O. baeti-
cum, and hence do not show the characteristic deflexed
fruiting pedicels of O. exscapum. In a similar way, all
Iberian cites of O. collinum should be rejected, since this
species bears leaves ciliate on the margins (cf. Gussone
1825; Garbari and Giordani 1984), whereas all studied
Iberian and Balearic plants show completely glabrous
Some authors have used the inflorescence structure
(Coutinho 1913, 1939; Aizpuru et al. 2000; Bolo
s and Vigo
2001) and/or the length of the floral bracts relative to their
pedicels (cf. Coutinho 1913, 1939; Zahariadi 1980; Bolo
and Vigo 2001) as diagnostic characters. In agreement with
those authors, our data show that O. divergens produces
wide inflorescences with very long and patent to deflexed
pedicels, with the length of the lowermost bract reaching
about half the length of its pedicel. On the contrary,
O. bourgaeanum and O. baeticum showed narrower inflo-
rescences with shorter and erect-patent to patent pedicels,
and the length of most of the bracts usually three-quarters
or more of the length of their pedicels (Table 4).
Morphology and size of the tepals have traditionally
been used to describe or to discriminate different taxa (cf.
Jordan and Fourreau 1866; Pastor 1987; Bolo
s and Vigo
2001). In fact, PCA shown in Fig. 1 revealed that the
length and width of the tepals represented an important
percentage of the variance (Table 2), mostly when the taxa
were compared by pairs. Thus, O. bourgaeanum produces
smaller tepals than O. divergens, although O. baeticum was
in an intermediate position and there was a wide overlap
between the taxa. Therefore, our studies revealed that the
flower characters vary widely, even in a single population
or individual, it being common that tepals are usually much
larger in the lower flowers of a given inflorescence. Hence,
they are only useful for differentiation between some par-
ticular taxa, and not in a global sense.
As previously remarked by Moret and Galland (1992),
the style length is as a crucial character to segregate
O. baeticum, with consistently longer styles, from
O. bourgaeanum and O. divergens, in which they are
shorter (Tables 3 and 4). This character itself allows an
easy and confident identification of herbarium sheets
lacking bulbs, leaves or capsules.
Capsule morphology is an interesting character to be
considered for taxonomy of the Iberian and Balearic taxa
of O. subg. Ornithogalum. Traditionally, segregation of
O. divergens (referred as O. umbellatum’) from O. bour-
gaeanum and O. baeticum (both united as ‘O. orthophyllum
subsp. baeticum’) has been based on the disposition of the
capsule ribs, which are equidistant in the former and
grouped by pairs in the two latter (cf. Coutinho 1913, 1939;
Zahariadi 1980; Pastor 1987; Aizpuru et al. 2000; Bolo
and Vigo 2001). However, the situation appears to be a bit
more complicated. On the one hand, capsules of O. di-
vergens bear six prominent and more or less equidistant
ribs (Fig. 5), a quite homogeneous character in this taxon.
On the other, capsules of O. baeticum are more or less
polygonal in section, with all the furrows between the ribs
(both on sutures and the midveins of the carpels) similarly
obtuse or flattened (Fig. 3) and not clearly paired. Finally,
capsules of O. bourgaeanum are extremely variable in size
and shape, although they can be recognized by the nar-
rower and acute furrows along the midveins of the carpels,
usually giving ribs a markedly paired appearance (Fig. 4).
Other features such as the shape and size of the
androecium, ovary and seeds are not absolutely conclusive
for the taxonomy of the three considered species. None-
theless, they are informative enough when combined with
other diagnostic characters.
Three types of seeds were described by Moret et al.
(1990) on the basis of the ornamentation pattern of testa
cells. Although these types were thought to characterize
different subgenera of Ornithogalum, a direct relationship
has not been demonstrated as shown by Coskuncelebi et al.
(2000) and Moret et al. (1990), who found more than one
seed type in various Eurasian sections of the genus.
However, all species of O
. subg. Ornithogalum show typi-
cally globose and slightly apiculate seeds with reticulate
testa (type 1, sensu Moret et al. 1990). Therefore, this testa
character can be regarded as an apomorphy of this group
(cf. Martı
n et al. 2010b).
The complex caryology of the Iberian and Balearic
members of O. subg. Ornithogalum is related to the high
frequency of ploidy, aneuploidy, translocations and dele-
tions (Neves 1952). All these processes have important
implications in the morphology and reproductive behaviour
of plants (van Raamsdonk 1986; Moret and Favereau 1991;
Moret and Galland 1992), since usually they constitute
reproductively isolated populations with autonomous
descendent lineages (van Raamsdonk 1985a, b) and can
generate morphological aggregates with complex taxon-
omy. Accordingly, some authors accept several species in
the polyploid complex of O. umbellatum sensu lato (Gad-
ella 1972; Gadella and van Raamsdonk 1981; Raamsdonk
1986), though others only accept just one variable species
with different ploidy levels (Moret and Galland 1992).
As deduced from previous morphological and cary-
ological combined studies carried out on Iberian plants,
O. bourgaeanum is mainly a diploid species (2n = 18)
or exceptionally triploid (2n = 27) (cf. Neves 1952, 1973;
n 1958;Lo
ve and Kjellquist 1973;
192 M. Martı
n et al.
Author's personal copy
n 1978; van Raamsdonk 1986; Moret et al. 1987;
Moret and Galland 1992), whereas O. divergens is usually
a hexaploid species (2n = 54) (cf. Neves 1952, 1956;
Gadella and van Raamsdonk 1981), both belonging to
the cited O. umbellatum complex’ (x = 9). Conversely,
O. baeticum is an amphidiploid (2n = 50, 52, 54; x = 25)
(cf. Ruiz-Rejo
n 1974, 1978; van Raamsdonk 1986; Moret
and Galland 1992) derived from an uncertain ancient
allopolyploid crossing, in which both a polyploid taxon of
the O. umbellatum complex and a relative of the current
lineage of O. platyphyllum Boiss. would act as presumed
parents (van Raamsdonk 1986). Therefore, Iberian cites of
O. gussonei Ten. (=O. tenuifolium Guss., non Redoute
Willkomm (1893), Ruiz-Rejo
n(1978) and Franco and
Rocha Afonso (1994) should be excluded, since it is an
eastern Mediterranean plant with chromosome number
2n = 14 (x = 7) (cf. Garbari and Tornadore 1971;
m 1989; Garbari et al. 2003), quite different from
the Iberian diploids 2n = 18 (x = 9). Moreover, it pro-
duces concolour and filiform leaves which have not been
observed in any Iberian material.
Preliminary results of the phylogenetic studies we are
carrying out based on sequences of plastid and nuclear
DNA regions (Martı
n et al. 2010b) place the taxa
of O. subg. Ornithogalum (incl. O. subg. Myogalum)ina
monophyletic clade, clearly apart from other Mediterra-
nean subgenera such as Cathissa or Beryllis. Furthermore,
our AFLP studies have also revealed a wide differentiation
among the three species here accepted (Martı
et al., unpublished data). Such molecular markers indicate
a closer position of O. bourgaeanum and O. divergens with
regard to O. baeticum, as suggested by van Raamsdonk
(1986) and Moret and Galland (1991) on the basis of
caryological and morphological data. Moreover, other
related European taxa such as O. orthophyllum, O. kochii,
O. exscapum, O. collinum and O. gussonei, show a suffi-
cient genetic differentiation from the Iberian and Balearic
populations, warranting recognition at the species rank
n et al., unpublished data). Conversely,
North African populations of O. algeriense are mixed with
those of O. baeticum, a result that supports synonymization
under the earlier name O. baeticum. In a similar way,
French populations of O. monticolum from the Maritime
Alps (its type locality) and Central Plateau, nest near the
base of all samples of O. bourgaeanum, with a very small
genetic distance. Aquaro and Peruzzi (2006) treated the
two taxa as belonging to two different lineages clearly
differing in the satellite type of one chromosome pair: the
former (treated as O. kochii subsp. monticolum (Jord. &
Fourr.) Peruzzi) showing terminal satellites, and the latter
(treated as O. orthophyllum subsp. baeticum) bearing
intercalary satellites. Their conclusion would also be sup-
ported by certain differences revealed by chromosome
banding (van Raamsdonk 1986). However, caryological
data reported previously by Moret et al. (
1987) show that
both terminal and intercalary satellites occur in different
Iberian populations (e.g. terminal in Leo
n, La Pola de
n, and intercalary in Madrid) of the diploid taxon
here accepted as O. bourgaeanum, and therefore are not a
diagnostic character for specific differentiation. Similarly,
van Raamsdonk (1985a, b) found that crosses between
French and Iberian diploid plants are fully compatible,
yielding similar or even higher seed sets than crosses
between only French diploid plants. All these molecular,
caryological and reproductive data together with the wide
morphological plasticity observed in wild populations of
the two taxa suggest treating O. bourgaeanum and O.
monticolum as synonyms. However, further molecular
studies are still needed to clarify the relationships
among all European and North African diploids of the
O. umbellatum complex’.

severe drought.
This species grows mainly in open mountainous stony and
relatively dry grasslands, although it can reach forests or
coastal areas, including marshes. In the Iberian Peninsula,
it ranges from sea level to 1,600 m altitude, although in
northern Africa it extends up to 2,600 m altitude in the

the south (Andalucı

a and east of Granada
and Jae
n), though some disjoint populations are found in
the centre (environs of Madrid) and north (Sistema Ibe
(Fig. 8).
O. baeticum exhibits a wide morphological variability in
leaves, flowers and inflorescences. Some individuals of the
type locality, including the holotype, are sometimes small,
much resembling O. bourgaeanum. This fact led several
authors (cf. van Raamsdonk 1986; Aquaro and Peruzii 2006)
to misunderstand the type of O. baeticum and to assimilate it
with O. bourgaeanum, leaving O. algeriense for most of
the southern Iberian populations. However, the style of
O. baeticum (including plants of the type locality) usually
reaches or exceeds 4 mm in length; the capsule morphology,
oblong, with flattened or obtuse furrows on both sutures and
midveins of carpels; and the glaucous colour of the young
leaves, allow easy differentiation between the two species.
Moreover, the type specimens of O. algeriense conserved at
LY bear styles about 4.5 mm in length (Thie
baut pers.
comm.), perfectly matching O. baeticum and hence justify-
ing synonymization of the two taxa. Preliminary results of
AFLP studies (Martı
n et al., unpublished data) also
support this solution. The disjoint populations of O. baeticum
from the north of the Iberian Peninsula were consistently
smaller than those from the south, probably due to their more
stressful high-altitude habitat. The actual populations of this
species are numerous and are composed of many individuals;
therefore, it seems that it is not endangered in short or
medium term. However, the disjoint populations in the north
are scarce and they are composed of few individuals;
therefore, the evolution of these populations should be fol-
lowed to evaluate their risk of decline or extinction in this
area. IUCN (2001) category: LC.
