Poa alpina L. ssp. alpina[FNA24, HC2]
alpine blue grass

Publication: Sp. Pl. 1: 67. 1753.

Origin: Native

selected vouchers: WTU

Notes: FNA24: "Poa alpina is a fairly common circumboreal forest species of subalpine to arctic habitats, extending south in the Rocky Mountains to Utah and Colorado in the west, and to the northern Great Lakes region in the east. It often grows in disturbed ground and is calciphilic. Poa √ógaspensis is a natural hybrid which seems to be between P. alpina and P. pratensis subsp. alpigena; it differs from P. alpina in its extravaginal branching, rhizomatous habit, and webbed calluses. The range of chromosome numbers suggests that P. alpina is predominantly apomictic.

Poa alpina subsp. alpina is the more common of the two subspecies. In the Flora region, it grows throughout the range of the species."
