Endemism of the Kazakhstan flora: Poaceae Barnhart

Abstract

A.N.Kupriyanov, P.D. Gudkova, E.A. Kruchkova

Endemic plants are a unique category of the flora geographical element, and they serve as the main criterion for distinguishing one flora from other ones. More than 60 years have passed since the last systematic processing of the Poaceae family within the flora of Kazakhstan. Since that time the status of many taxa of Kazakhstan grasses has changed. The paper presents a complete checklist of species of the Poaceae family endemic to Kazakhstan, including references, synonyms, ecological preferences and geographic distributions in Kazakhstan for each species. A total of 57 endemic grass species are found in Kazakhstan: Stipa (17), Elymus (17), Elymotrigia (10), Leymus (3), Agrotrigia (2) and Poa (2), and one species of Agropyron, Agrostis, Elytrigia, Koeleria, Phleum, and Puccinellia each. Four species have been found in other countries, and 21 species of the Kazakhstan flora have lost their endemic status due to new taxonomic treatment.
