|discussion=<p><i>Poa abbreviata </i>subsp.<i> pattersonii</i> is an alpine taxon that extends from the Brooks Range, Alaska, to the Sierra <i>Nevada</i>, California, where it is rare, and through the Rocky Mountains to southern Colorado. It also grows in the Russian Far East. It is often confused in herbaria with <i>P. glauca</i> (p. 576), but differs in having predominantly intravaginal branching, an abundance of vegetative shoots, and usually shorter anthers. Plants from northern British Columbia to Alaska and Russia have been called <i>P. abbreviata</i> subsp. jordalii (A.E. Porsild) Hulten. They have webbed calluses, very short (occasionally nonexistent) lemma hairs, panicles often exserted well above the basal tuft of leaves, and particularly slender culms.</p>
