(Fig. 12.). / f Fig. 12.—Seeds of alpine meadow grass (Poa nlpina): a and b, back views; o-e, side views; f-h, front views; h, a terminal floret. The seed of Poa al/pina is not on the market and is not likely to be found in commercial seeds. Individual seeds of 1\ nlpina closely resemble those of P. annua, but are to be distinguished by the indis- tinct intermediate veins of the glume, the variable raehilla segment, and especially by the keels of the palea, which are slenderer, not arched, less pubescent, and strictly hispid-ciliate above. The plant is alpine and occurs in the northern part of the United States as far west as Colorado, in Canada and Alaska, and in Europe and Asia. Poa sudetica Haenke. Spikelets 2 or 3 flowered; florets 3—4 mm. long, lanceolate or ovate-lanceolate; apex acute or acuminate; glume somewhat arched and strongly keeled at the back, light brown or dark brown, sometimes tinged with purple; margins of the glume narrowly infolded below the middle, narrowly hyaline-edged above the middle and not flaring at the apex; all the veins distinct, never silky pubescent, usually hispid;.
