Distribution of bluegrasses. portant California perennial bluegrasses are: muttongrass, pine bluegrass, Olney bluegrass, skyline bluegrass, Pringle blue- grass, Hansen bluegrass, Pacific blue- grass, and Nevada bluegrass. Annuals: Annual bluegrasses occur in the more arid sections of the state. Several afford some early grazing in the deserts and foothills. Of these, only an- nual bluegrass (P. annua) is important as forage. Key to Species The authors are indebted to Dr. David A. Keck for his preparation of the accompanying key of Poa. Plants annual. Commonly a dooryard weed; widespread at low elevations 11. P. annua Plants perennial Creeping rhizomes present Panicle open, pyramidal, its elongated lower branches lax and floriferous only in outer half; culms round Lemmas glabrous or puberulent but not webbed at base; florets all female; rhi- zomes short. High montane 5. P. nervosa Lemmas with a tuft of cobwebby hairs at base; florets perfect; forming dense sods; very common 1. P. pratensis Panicle more contracted, oblong, its short lower branches not lax; lemmas not con- spicuously webbed at base; forming thin sods; culms flattened, 2-edged; not com- mon 2. P. compressa Creeping rhizomes wanting; lemmas not webbed at base. All bunchgrasses Lemmas glabr
