Many realistic biological images were found by the authors in the painting 'Haymaking' of the famous Russian and Soviet artist Arkady A. Plastov, representing more than 50 taxa of plants and insects. The painting reflects the meadow/forest edge ecotope in the central part of European Russia. Phenology and ecology of depicted botanical and entomolog...
The origin of more than half of cultivars of the genus Hedera L. known to date is not documented. Assumptions about the relationship of cultivars have traditionally been based on a speculative assessment of their morphological similarity, but this method, as our research shows, often proves unreliable. We have developed a method for the historical...
New cultivars of ivy are obtained only by identifying, selecting and stabilizing vegetative mutations - sports. Historically, ivy cultivars form a linear sequence in which each given cultivar is preceded by one mother cultivar. However, along with morphologically new mutations, “old” mutations with already known combinations of traits may reappear...
For the first time, the geographical aspects of the study of ivy cultivars, a valuable ornamental foliage
plant, are considered. The role of some countries in the creation of a modern assortment that numbers 1354
cultivars is analyzed. In total, 25 countries participated in ivy selection, which are divided into five groups
according to their con...
Pistacia atlantica Desf. is the only native species of the genus in the Crimean flora with the northernmost exclave of its Mediterranean – Western Asian area here. It is a relic and protected species. Authors made a first-ever discovery of P. atlantica with variegated leaves among the fragmented open woodland of Submediterranean shibljak in the vic...
One further old British ivy cultivar ‘Glymii’ is revealed and identified in the arboretum of Nikitsky botanical garden. It has persisted here as a relict of cultivation since the XIX century. Morphological characters specific to the cultivar’s leaf blades in plants examined fit completely the authentic descriptions and images available in the liter...
The genus Atriplex L. (Chenopodiaceae) includes many weed and ruderal plant species.
Until recently, 11 species of this genus were recorded in the natural flora of the Crimean peninsula. The authors discovered in the Crimea populations of A. sphaeromorpha, a species which had not previously been included in the lists of the natural flora of the Crime...
Unlike other cultivated plants, the selection of ivy (Hedera L.) is associated not with hybridization, but with revealing,
sampling, and fixing spontaneous vegetative mutations called sports. Therefore, ivy cultivars historically form a linear
sequence in which each cultivar is preceded by one parent. Vegetative mutations of ivy cultivars are divid...
The article describes a gallery of ancient petroglyphs preserved on a horizontal slab of Sarmatian limestone in the Kara-Khoja stow in the Crimean Plain, on the eastern periphery of the Tarkhankut elevated plain, nine kilometers north of the village Voikovo. The exposed section of the rock with petroglyphs has an area of 60 square meters. The first...
Unlike most other cultivated plants that undergo targeted hybridization, the selection of ivy (Hedera L.) is associated
with the revealing, sampling, and fixing spontaneous vegetative mutations called sports. Vegetative, or somatic mutations
occur rather rarely – not more often than once a decade in about half of the ivy varieties in case of absenc...
Arrowhead' , 'Deltoidea' , 'Star' , 'Duck Foot' и даже 'Dragon Claw'. Видите их? Когда-то курчавый 'Curly Locks' просто сразил гения метафоры Андрея Вознесенского: лепестки гипертрофированные, как парики питергофрированные. А тот неброский плющ, который я так долго не мог опознать, оказался всеми забытым сортом 'Scutifolia'. С латинского название п...
Our hypothesis is that a variety of particularly complex forms appears at later stages in the history of ivy cultivation, i.e., in historically younger cultivars
A description of a new cultivar Hedera helix 'Peregreenus' is given. In the course of the trial, peculiarities of vegetative mutations in the line of its six ancestor cultivars are traced. Evidence on certain patterns in the development of variegated ivy bud mutations is discussed. A manifestation of the law of homologous series in hereditary varia...
With this paper we continue a new annual series, the main purpose of which is to make significant floristic findings from Russia and neighboring countries more visible in Russia and abroad. In total, this paper presents new records for 48 vascular plant species from 6 Eurasian countries, obtained during field explorations, as well as during taxonom...
Problems of the history of cultivation of taxa and culta of the genus Hedera in Nikitsky botanical garden are analyzed. Data on the genus Hedera is revealed to be incomplete and contradictory or absent at all on the various stage of the Garden history. The most important impetus to ivy collection development was given by N.A. Hartwiss and L.I. Ulei...
By the method of data re-collection and re-assessment, we here test the completeness of distribution areas of the species and species aggregates of Rosa in Eastern Europe as mapped in volume 13 of Atlas Florae Europaeae (AFE), and discuss insights into the issues connected with the data. We found many new occurrences which are additions to the publ...
The article deals with the finding of Melica altissima L. in the Crimea. The species was listed for the region by J. G. Georgi as far back as 1800, but since then has been considered as missing in the Crimea.
When one describes some plants, there are cases when natural selection produces cultivars, and the products of selective breeding appear to be species. The majority of specialists in fundamental and applied botany do not pay respective attention to this problem. Meanwhile, despite the formal following of the rules of respective Codes, there is a di...
New data on some critical taxa of Pinophyta in Ukrainian flora are given and discussed
with presenting identification keys. Next taxa are treated: Ephedra arborea Lag. – as
synonym of E. distachya L., Pinus pallasiana Lamb. – as P. nigra J. F. Arnold subsp.
pallasiana (Lamb.), P. pityusa Steven var. stankewiczii Sukacz. – as P. brutia Ten. var.

An old British ivy cultivar ‘Cavendishii’ is revealed in the arboretum of Nikitsky botanical garden. It has persisted here as relict of cultivation since the XIX century. Stellate brushy trichomes on leaf blades evidence the plant belongs to H. helix. Morphological characters specific to the cultivar’s leaf blades in plants examined fit completely...
Resolution of the conference is presented.
The genus Holosteum L. distributed mostly in temperate Eurasia has very confused taxonomy. Modern estimation of the species richness varies from one species worldwide to seven species occurring just in Eastern Europe. One of the most problematic species of the genus is H. glutinosum (M. Bieb.) Fisch. et C. A. Mey. usually treated as a subspecies or...
The data on 11 plant taxa, new to the Crimea, are presented. The taxonomical and phytogeographical considerations are also discussed.
An old British cultivar of Hedera hibernica ‘Scutifolia’ was identified in the arboretum of Nikitsky botanical garden. The most likely, it has persisted here as relict of cultivation since the early XIX century. Up to now, no one ivy cultivar introduced by first directors of the Garden has been considered to be survived. Specific stellate adpressed...
Specific problems of selection and study of Hedera cultivars are elucidated
The two old English cultivars of Hedera helix, 'Angularis' and 'Scutifolia' are re-discovered in the arboretum of Nikitsky botanical garden. The most likely, they have persisted here as relicts of cultivation since the early XIX century. Up to now, no one ivy cultivar introduced by first directors of the Garden has been considered to be survived.
A highly ornamental sort of the tree of heaven {Ailanthus altissima (Mill.) Swingle, fam. Simaroubaceae) with bright creamy-white variegation of leaves is found among its neglected thicket in Simferopol in 2017. Three-year male creeping-rooted plant with vegetative mutation on it has been observed by authors during additional two years and is descr...

Senecio tauricus (Asteraceae) was described as an endemic species restricted to the mountain plateaus (yailas) of the Crimean Peninsula, growing only in meadow-steppe plant communities. The species status for this taxon was accepted in all relevant floras, identification manuals, and checklists; it is also listed in the current edition of the Red D...
Holosteum marginatum C. A. Mey. was firstly reported from the Crimea by H. E. Grosset in 1977 on the base of his findings in the central part of the Crimean Mountains (Mt Chatyrdag and Mt Demerdji) in 1958. That record was generally either omitted or considered to be doubtful by following florists because H. E. Grosset did not in¬dicate the herbari...

Annotated plant lists and information on soil and land use of the major Crimean biodiversity hotspots are presented. The floristical diversity of the Crimea is analysed. Nature conservation, historical, cultural, and sustainable development considerations are discussed. An extensive list of literature on the Crimean environment is attached. Zusamme...
The Crimean taxon at issue has long been known as Stankiewicz pine with continuing discussion around its taxonomical rank and origin. In 1995, the authors discovered the new isolated population of the taxon on Papayakaya Mt. in Crimean Sub-Mediterranean. Due to hypothetical paleogeographic reconstruc-tion of Pleistocene coastal landscapes here, tog...
The Crimea is a Ukrainian region of great botanical interest due to its high floristic and chorological diversity. For proper mapping of the Crimean flora it is necessary to add five extra grid cells on the base map of Atlas Florae Europaeae.
Estimates of the number of narrow Crimean endemics have been revised over 30 times since 1856 and have varied strongly, ranging from 10 to 300 species. According to the author's recent revision, endemics in the Crimea number approximately 130 species and subspecies. Comparisons with similar in size regions indicate that the estimate of the Crimean...

Dear colleagues, who have experience in identifying Barbarea spp., please help! It is believed that only Barbarea arcuata exists in Crimea (IMG_2441), but it seems to me that the second specimen (IMG_2442) belongs to another species, somewhat similar to B. balcana. All specimens were collected in Crimean Mts. Your help will be acknowledged.
I have failed in finding any new taxonomical paper devoted to these taxa as well as any difference between them. I am afraid our understanding of the european species of the genus has remained how it is shown in the Flora Europaea. Please any hint.
I have a big collection of ivy (Hedera) but fail to identify this specimen as species. It has matt leaves all of the similar shapes and with unusual stellate trichomes of 7-8 (10) rays - nearly scale-like but of fully fr
ee rays. The trichomes of this specimen do differ from those of other Hedera species. This specimen came from a Saint Petersburg's Botanical garden but of unknown origin. I took the photo of the specimen in my garden. The help will be acknowledged.
My colleagues an I have found a very old Taxux tree in Crimean Mts. Can morphometric data of the trunk be useful for rather plausible inferring its age? Please help with advice!
Dear Colleagues,
I ask your help to designate the term "natural flora" .
I understand "natural flora" as spontaneous, wild flora of a region, which encompasses only residental taxa including archaeophytes and neophytes but excluding non-residental species like ephemerophytes, cultivated or relicts of cultivation. Some florists still include non-residents in their floristic lists and unfortunetely this tradition prevails in post-Sovien area. This leads to deformation of our knowledge of extant plant cover, plant geography etc.
I find it is difficult to argue with those who regects the frames of natural flora. At the same time those who deals with natural flora do not explain properly their understanding of the subject.
So I need for additional arguments to make the term more convincing.
Thank you in advance!
Pedicels and calix are covered with glandular trichomes, the number of leaflets runs 21.
