Prairie threeawn (Aristida oligantha). rigid ascending or spreading culms 1-2 ft (30-60 cm) long, and long blades; panicle Vs-1/^ the entire length of the plant, the branches stiffly spreading; spikelets appressed to the branches, glumes cm long, the lemma nearly equal; awns not widely spreading, mostly about 2 cm long, the lateral a little shorter than the central. Distribution and habitat: Formerly in- cluded in spreading threeawn (Aristida divaricata), Arizona threeawn is a deep- rooted perennial which occurs on flats and gravelly hills up to 4000 ft. It is found commonly in the lower Sacramento and upper San Joaquin valleys and along the coast of southern California below Los Angeles. It does well on south and west exposures where, on the foothill ranges, it is associated with needlegrasses and squirreltails. The coarse basal leaf- age is not highly relished by livestock except in early spring and late autumn after the seed has dropped and other for- age is scarce. Stands are most abundant on heavily grazed ranges. 32. DROOPING WOODREED (CINNA LATIFOLIA) Drooping woodreed is a tall slender perennial with flat blades 10—15 mm wide; panicle very loose, drooping, the branches spikelet-bearing towards the ends; spikelets falling entire, glumes and lemma equal, the floret on a minute stalk, lemma with a minute awn from below the tip. (Fig. 97.) Distribution and habitat: Drooping woodreed is the only species of this genus found in California. It occurs at middle. Fig. 97. Drooping woodreed (Cinna latifolia). [103].
