Amphi-Beringian distribution of Poa pseudoabbreviata based on Hulten (1968), Probatova (1985) and Tzvelev (1964) (•) with new localities in northern Yukon Territory and northwestern Alaska (A). Poa pseudoabbreviata is a loosely tufted plant with culms 5 to 20 cm in height, well above a basal tuft of short and narrow leaves; the panicle is ovate with its branches long, slender, and usually lax and glabrous; the glumes are glabrous; the lemmas are glabrous between the basally puberulent keel and marginal nerves; the anthers measure t

There is no webby tuft on the lemma callus. It is reported from rocky slopes and snow beds in Alaska (Hulten 1968) and stony tundras and bald mountain peaks in the far eastern USSR (Tzvelev 1976).
