Abstract

Aims. The analysis of the herbarium collection (KWHA) of the M. M Gryshko National Botanic Garden NAS of Ukraine and to identify of its rarity fraction were the objectives of our studies. Methods. Herbarium collection of the Gryshko NBG NAS of Ukraine (KWHA), Internet resource "Red Books" of the Caucasian region, plant names are given according to Plant List (Plant List) and the catalog KWHA (Kataloh KWHA, n.d.), the presence of endemicity was verified with the GBIF system. Results. The fraction of plants collected in the Caucasus region was selected according to the KWHA catalog. The time of formation of the main collection was 50–70s of the ХХ century. There has been found a folder of Herbarium specimens, dated the 50s of the last century. The collector of these specimens is marked V. G. Tanfíl'ev, who had studied, collected, and systematized the plants of the Stavropol region for a long time. These 147 sheets were added to the existing collection of Caucasian plants. There are 2847 species of Caucasian plants in KWHA herbarium collection now. Plants belong to 7 classes, 149 families, and 860 genera. The number of species listed in the Red Books of the Caucasus is 460, including 115 endemic species. Conclusions. During the study of the herbarium collection KWHA the group of plants collected in the Caucasian region was highlighted. This group has 2847 species, which is slightly less than half of the total number of Caucasus flora species. They belong to 7 classes, 149 families, and 860 genera and were collected in different places of the Caucasus. The collection has been replenished with 16 new species thanks to the new archival finds. The rarity fraction of the Caucasian collection, 460 species, is especially valuable because they have conservation status. There are 115 endemics of the Caucasus among them.
