Bromus paulsenii Hack.

+ Rf(CS): Russia: Dagestan, Dokuzparinsky district, Mount Shalbuzdag, 41°20'07.4''N, 47°48'38.1''E, 3500 m, on rocky slopes in the nival zone, 30 Jul 2022, Murtazaliev (DAG, LENUD).

– The species is reported for the first time for Russia and for the entire Caucasus. This locality is the westernmost point in the known area of the species. The main area of the species is in the mountains of C Asia. Bromus paulsenii is polymorphic in many features, especially in the size of the spikelets, the number of flowers in the spikelet, the pubescence of the leaves, etc. Due to the strong variability of B. paulsenii, several new species ( B. angrenicus Drobow, B. pamiricus Drobow, B. turkestanicus Drobow) were described, which are now considered to be its synonyms (Komarov 1934). Bromus paulsenii is closest to B. variegatus M. Bieb., from which it differs in smaller panicles (5–6 cm long) and inflorescence branches not exceeding the length of spikelets. The main morphological features of the species are that leaf sheaths are articulated and the stem grows almost horizontally.
