10. P. hispidus Gray. Stem diffusely much-branched, 3 to 7 inches high ; lierb- 

 age spreading-bristly; leaf -blades lanceolate to oblong, 14 to 1 inch long; spikes 

 reduced to close glomerules borne at the ends of the branches or in the axils, the 

 glomerules 2 to 6 lines long; corolla V2 line wide; nutlet 1, broadly ovoid with 

 shortly acute inturued apex, 3-ribbed on back or the ribs sometimes obscure, thickly 

 tuberculate and sometimes interruptedly rugulose or short-rugulose; caruncle set 

 ventrally above middle of nutlet under the incurved apex. 



Gravelly soil or sandy ground of flats, (3500 or) 5000 to 9000 feet: east and 

 north side of the Sierra Nevada from Mono Co. to eastern Siskiyou Co. Extending 

 to western Nevada and north to eastern Oregon. June-Aug. 



Tax. note. — The nutlet of Plagiobothrys hispidus is unlike that in any other of our species. 

 It is in a marked degree borne horizontally, a position associated with the position of the scar 

 above the middle of the nutlet. Dorsally the nutlet is 3-ribbed with the median rib the stronger. 

 Between the ribs lie shallowly troughed intervals. The surface of the nutlets, both dorsally and 

 ventrally, is irregularly and rather finely tuberculate on a microscopically papillate ground.
