Publication: Bot. Mater. Gerb. Bot. Inst. Komarova Acad. Nauk SSSR 20: 429. 1960.

Origin: Introduced from Eurasia

selected vouchers: WTU

Notes: FNA24: "Leymus racemosus is native to Europe and central Asia, where it grows on dry, sandy soils. It has been introduced into the Flora region, and collected at various locations, particularly in the northwestern contiguous United States; it is not clear how many of the populations represented by these specimens are still extant. Tsvelev (1976) recognized 4 subspecies. Because there are few North American specimens, and these are incomplete, no attempt has been made to determine to which subspecies the North American plants belong."
