 what strigose. Leaves linear to narrowly lanceolate, 2-3 cm. or rarely 5 cm. long, 1-4 mm.

 at base; spikes often solitary, 5-15 cm. long, bractless or the lowermost flowers sometimes 

 bracteate ; corolla 1-2 mm. broad ; fruiting calyx 4-7 mm. long, crowded or distant, tube 

 rounded-obconic at base, lobes linear or linear-lanceolate, more or less connivent, midrib thickened, 

 tawny-hispid, margins strigose-hirsute ; nutlets 4, broadly ovoid, 1.6-2 mm. long, granulate 

 and tuberculate or rarely nearly smooth toward the base, sides obtuse and rounded, groove 

 closed or somewhat dilated at the always forked base; gynobase two-thirds the length of the 

 nutlet ; style reaching to the apex of nutlet or a little shorter. 



Dry slopes and ridges, open pine forests and sagebrush. Arid Transition Zone; Klickitat and Walla Walla
