Abstract

A new species Agropyron tuvinicum A. Korolyuk, Melnikov et Laktionov is described from Southern Siberia and Eastern Kazakhstan. The new species differs from all closely related ones by rachides and rachillas pubescent only along their ribs, rather than throughout the surface. It differs from A. cristatum (L.) Gaertn. by narrower and looser spike, and from A. mongolicum Keng by wider spike and longer anthers. It primarily inhabits sandy and rocky steppes. Its main range is located in the Republic of Tuva, but it was found in adjacent territories.


Key words: Agropyron, Altai, Khakassia, Tuva, Western Sayan, East Kazakhstan Region, new species
