Banks of streams at Santa Barbara {Parry) ; also in the island of Hawaii. 



C. ScHOTTii, Dewey, 1. c. 25, an imperfectly defined species from Santa Barbara {Parry'), 

 would appear to belong here. The spikes are cylindrical, very slendei', the male 3 to 5, and 3 

 inches long, the female 3 or 4 and 4 to 8 inches long, loosely flowered, unequally peduncled : 

 bracts foliaceous, with long .sheaths ; leaves and bracts glaucous : scales dark red, oblong, obovate, 

 scarcely acute : fruit abortive. 



C. Watsoni, Olney, Bot. King Exp. 370, is founded upon specimens too young for satisfactory 

 description. The stem is 18 inches high, shorter than the upper leaves : spikelets 7, the male 4, 

 the uppeiTiiost largest and the rest .short, all aggregated ; scales claret-colored, lanceolate, hispid, 

 aristate, ciliate at the apex, the male 3-nerved : perigynium deeply cleft, the bifid beak sjireading 

 and slightly hairy. Collected at the base of the Washoe Mountains, near Carson City, Nevada,
