Chromosome numbers (2n) for 13 rare, endemic plant species (19 populations) from the families: Asparagaceae, Asteraceae, Boraginaceae, Brassicaceae, Caryophillaceae, Euphorbiaceae, Plantaginaceae – are reported on the material from Mongolia. For Euphorbia potaninii Prokh. (2n = 20), Smelowskia altaica (Pobed.) Botsch. (2n = 14) chromosome complements were examined for the first time. Chromosome numbers of Askellia flexuosa (Ledeb.) W. A. Weber (2n = 42), Cirsium arvense var. vestitum Wimm. et Grab. (2n = 34), Crepis crocea (Lam.) Babc. (2n = 16), Eremogone meyerii (Fenzl) Ikonn. (2n = 44), Heterochroa desertorum Bunge (2n = 34), Plantago komarovii Pavl. (2n= 10, 12), Rhinactinidia eremophila (Bunge) Novopokr. ex Botsch. (2n = 36) were determined from Mongolia for the first time. New cytotypes for Anoplocaryum compressum (Turcz.) Ledeb. (2х) and Eremogone meyerii (4x) were studied. For the species of Plantago komarovii, the phenomenon of aneuploidy (2x = 10) was described for the first time. For each species the area and published data on karyology are given.

For the first time we describe the morphology and anatomy of mature achenes bearing fertile seeds of Pietrosia laevitomentosa, an endemic plant species in the Eastern Carpathians. The new diagnostic features of the genus Pietrosia justify its taxonomic recognition as separate from Andryala; those are the achene size (between 2.5 and 4.3 mm long), the deciduous pappus, the single-rimmed achene apex, the elongate exocarpic cells, the complete ring of mesocarpic sclerenchyma (up to 11-layered), and the number and localization of the vascular bundles (5 bundles, in the small ribs). Furthermore, our data may also serve to reconsider the species ecology and conservation strategies.

Many plant species require the services of an animal pollinator. In Hawai'i most endemic plant species are declining, yet their pollinators are often unknown because floral visitors are uncommon, or because visits occur at night, making them difficult to observe. Information about the pollination ecology of rare plants is needed to help develop a conservation strategy. We used an automated, infrared-equipped video system to record animal visits to the flowers of rare plant species on the island of O'ahu, Hawaii. Over 500 hours of recordings were made on four plant species. For the first time, a nocturnal moth was observed visiting Cyrtandra hawaiensis. Also for the first time, native masked bees, presumed to be Hylaeus connectans, were recorded visiting the flowers of two endangered lobeliads, Cyanea pinnatifida and Cyanea superba. An introduced bird, the Japanese White-eye Zosterops japonicus also visited the Cyanea species, but it appeared to act as a nectar robber. A third lobeliad, Clermontia kakeana, was observed continuously for several days and nights but only visits by ants were recorded and no fruits were produced. While it was not always possible to determine the actual species of invertebrate floral visitors, the continuous nature of our video recording allowed us to document floral visitors that were not previously known. Furthermore, the recordings can be made without potential artefacts introduced by the presence of human observers near the flowers. This methodology can be used to document many difficult-to-observe ecological interactions between animals and rare plants.

Plant Endemism

Endemism is an important criterion for identification of floristic regions and determination of floristic properties of these regions. Turkey is one of the world’s major countries in terms of endemism over 3.000 endemic plant species. This study was carried out in order to determine the floristic composition and endemic plant species on the serpentine and marble (metamorphic rocks) parent material in semi-arid garssland in Çankırı-Eldivan. For this reason plant samples were collected in different growing season in 2014 (month of between April- September), approximately 4ha (Marble, 3.88 ha; Serpentine, 0.08 ha) area in Çankırı-Eldivan. Study area is located A4 square according to the grid system of P.H. Davis (1965-1988) and Irano-Turanian region in phytogeographic respect. As a result of the plant sampling carried out in the area; 16 families, 27 genera, 31 species determined in serpentine parent material. Among of these plants 9 of them are endemic plant. Endemism rate of the serpentine area is 29%. In addition, 20 families, 58 genera, 72 species of plants have been identified in marble parent material and 14 plant taxa of these species endemic. Endemism ratio is 19%. Results of this study showed that parent material effects of plant diversity and endemism ratio.

Hladnikia pastinacifolia, the most prominent endemic plant species in Slovenia, is rare and protected because it is a stenoendemic and paleoendemic species restricted to area of Trnovski gozd (W Slovenia). However, this species can be found in various habitats. The disparity between the non-specific habitat preference of the species and its rarity has not been sufficiently explained. Here we focus on the functional morphological features that are most indicative for the ecology of plant species: the anatomical and morphological characteristics of leaves. Hladnikia pastinacifolia exhibits heterophylly during ontogeny (heteroblasty). We aimed to describe and compare the anatomical characteristics of three H. pastinacifolia leaf morphotypes among them and in relation to various habitats. Therefore, we compared leaf functional features that are indicative for the ecology of plant species: the thickness of the leaf lamina, the spongy and palisade parenchyma, the thickness of the upper and lower epidermis and the number of leaf stomata in the upper and lower epidermis. These measurements were further used to calculate the ratio between the spongy and palisade parenchyma, leaf stomata index and the density of leaf stomata. We determined that the H. pastinacifolia heteroblasty belongs to the Apium-type. Results showed that the five-pinnate leaves were the most distinct type, being the thickest, with the highest numbers of stomata abaxially. When compared among habitats, leaves from the scree habitat were the thickest according to all the tissue layers studied. The indices calculated were less useful for the distinction between leaf types and habitats.

Abstract. Associations between ants and plants may be described, in some cases, as mutualisms. Ants use plant structures as sites for nesting and in return they offer protection against herbivory. This paper reports for the first time the association between Pseudomyrmex acanthobius Emery nest in subterranean structures of Aspilia grazielae J.U.Santos, an endangered endemic plant species, in Corumbá, Pantanal domain. Additionally, this record reveals a new aspect of the ecological niche and extends the geographic distribution of P. acanthobius.Primeiro Registro de Pseudomyrmex acanthobius Emery no Pantanal BrasileiroResumo. A associação entre formigas e plantas pode ser descrita em alguns casos como mutualismo. Estruturas de plantas, como locais de nidificação, atraem algumas espécies de formigas em troca da proteção anti-herbivoria. Este trabalho registra pela primeira vez a nidificação de Pseudomyrmex acanthobius Emery em estrutura subterrânea de Aspilia grazielae J.U.Santos, espécie endêmica e ameaçada de extinção na região de Corumbá, no domínio Pantanal. Adicionalmente, esse registro revela nova amplitude do nicho ecológico e amplia a distribuição geográfica prevista de P. acanthobius.

Our study showed that the anthropogenic impact on the flora of the study area, including agricultural activities, is growing every year. This complex research has been conducted in Almaty Province on the 6 populations of the four rare and endemic plant species (Ikonnikovia kaufmanniana, Limonium michelsonii), taking into account the total number, age spectrum. An analysis of the density and age structure of the populations Ikonnikovia kaufmanniana showed that the age range of the population 1 and 2 account for maximum virginal individuals and in the population of 3 generative individuals. The results of the study of the age and condition of life Limonium michelsonii in different parts of the three populations showed that a young virginal (64.6%) and generative individuals (23.6%) and in the population 2, the maximum is in juvenile (54.5%) and (20.49%) individuals and population 3 maximum occurs at a young virginal (38.9%) and (29.4%) individuals.
