<abstract xmlns="http://www.w3.org/1999/xhtml">Historical and current occurrence of halophytic species <italic>Carex divisa</italic> was studied in Slovakia during 2003–2014. It is known only in the Podunajská nížina Lowland, SW Slovakia, where 19 sites were found in total including historical and recent locations. Recently, the number of records decreased markedly and we confirmed only 9 localities. Due to the sharp reduction in the number of sites and appropriate habitats, <italic>Carex divisa</italic> is re-evaluated as endangered (EN) plant species of the Slovak flora.</abstract>

<italic>Carex divisa</italic> in Slovakia: overlooked or rare sedge species?

<abstract xmlns="http://www.w3.org/1999/xhtml">The group of <italic>Epipactis helleborine</italic> s.l. includes several subspecies. A new subspecies <italic>Epipactis helleborine</italic> subsp. <italic>moratoria</italic> was determined in Slovenia in 2015. It thrives in mixed wood in a region of Gorica at Raztez. Morphologic and phenomenological comparison confirmed clear differences between <italic>E. helleborine</italic> subsp. <italic>moratoria</italic> and <italic>E. helleborine</italic> subsp. <italic>helleborine</italic>. The characteristic differences seen in <italic>E. helleborine</italic> subsp. <italic>moratoria</italic> are the stem which is more or less bent at the level of the leaf base, the plants are smaller and more slender than <italic>E. helleborine</italic>, there are also differences in the flowers and the leaves. The ovary in <italic>E. moratoria</italic> is often in a horizontal position, especially at the time of fruiting, wheras in <italic>E. helleborine</italic> ovary usually hangs down. All of the wild orchids in Slovenia are protected species and among them it is <italic>Epipactis helleborine</italic> subsp. <italic>moratoria</italic> which, up till now is only known at one site.</abstract>

<italic>Epipactis helleborine</italic> (L.) Crantz subsp. <italic>moratoria</italic> A. Riechelmann &amp; A. Zirnsack., a new subspecies of Broad-leaved Helleborine in Slovenia

<abstract xmlns="http://www.w3.org/1999/xhtml">There are 15 plant species included in the Russian Red Book, which occur in the Republic of Mordovia: <italic>Najas tenuissima</italic>, <italic>Koeleria sclerophylla</italic>, <italic>Stipa dasyphylla</italic>, <italic>S. pennata</italic>, <italic>S. pulcherrima</italic>, <italic>S. zalesskii</italic>, <italic>Fritillaria ruthenica</italic>, <italic>Iris aphylla</italic>, <italic>Cypripedium calceolus</italic>, <italic>Cephalanthera rubra</italic>, <italic>Epipogium aphyllum</italic>, <italic>Neottianthe cucullata</italic>, <italic>Orchis militaris</italic>, <italic>Neotinea ustulata</italic>, <italic>Thymus cimicinus</italic>. Of these, only <italic>C. calceolus</italic> is included in the Global Red List as Critically Endangered. Threat status for studied species in Mordovia was assessed, and their distribution dynamics in this region throughout 12 years was described. Recent floristic studies, inspections of herbariums and literature were used for searches all provided data. Grid mapping and IUCN criteria were used. Nine taxa were determined as Critically Endangered, three as Endangered, one as Vulnerable, one as Near Threatened and one as Data Deficient. The areas of occupancy and extent of occurrence in Mordovia were assessed for each taxon. All studied species should be included in the next edition of the Mordovian Red Book. <italic>F. ruthenica</italic>, <italic>E. aphyllum</italic>, <italic>N. ustulata</italic>, <italic>T. cimicinus</italic> require additional studies to confirm earlier observations.</abstract>

IUCN guidelines using for assessment of plants from the Red Book of Russian Federation at regional level: a case study for the Republic of Mordovia (Russia)

<abstract xmlns="http://www.w3.org/1999/xhtml">Sixteen endemic plant taxa were selected from Kosovo, according to the IUCN standards and for each taxon the risk assessment and threat category has been assigned. The taxa were compared with their previous status from fifteen years ago. From sixteen plant taxa, which were included in this work, four are Balkan endemics, whereas, eight of them are local endemics and four of the taxa are stenoendemics. Six of the taxa are grown exclusively on serpentine soils, five of them on limestone substrate, four of them in carbonate substrate, yet only one in silicate substrate. The work has been done based on the standard working methodologies of the IUCN (Guidelines for Using the IUCN Red List Categories and Criteria – Version 8.1). The most threatened plant taxa is <italic>Solenanthus krasniqii</italic> – which after its observance has only 20 mature individuals. As a result of the wild collection of the medicinal and aromatic plants, from the local population, <italic>Sideritis scardica</italic> is about to be completely go extinct. The aim of this study was to assess the state of endemics in the threats possessed to them during the previous times, present and predicting the trends for the upcoming years.</abstract>

Conservation assessment of the endemic plants from Kosovo

<abstract xmlns="http://www.w3.org/1999/xhtml">We conducted a phytosociological analysis of more than 250 relevés in the Julian Alps and compared them with similar communities elsewhere in the Alps and in the Dinaric Alps to describe the following new syntaxa of alpine swards and heathlands from the alliance <italic>Caricion firmae</italic> (class <italic>Elyno-Seslerietea</italic>): <italic>Saxifrago squarrosae-Caricetum mucronatae, Saussureo pygmaeae-Caricetum rupestris, Seslerio sphaerocephalae-Dryadetum octopetalae, Homogyno discoloris-Vaccinietum gaultherioidis, Saxifrago paniculatae-Caricetum fuliginosae</italic> and <italic>Homogyno discoloris-Loiseleurietum caricetosum firmae,</italic> the new association <italic>Achilleo clavennae-Elynetum myosuroidis</italic> from the alliance <italic>Oxytropido-Elynion</italic> and two new syntaxa from the alliance <italic>Loiseleurio-Vaccinion</italic> (class <italic>Loiseleurio-Vaccinietea</italic>): <italic>Homogyno alpinae-Vaccinietum gaultherioidis</italic> and <italic>Empetro-Vaccinietum gaultherioidis rhododendretosum hirsuti</italic>. Many species that are rare, of conservation concern or protected in Slovenia occur in the newly described communities.</abstract>
