Culms slender from slender rootstocks, 1-1.5 dm. tall; 

 spikelet linear-lanceolate, acute, 1-1.5 cm. long; scales ovate 

 to ovate-oblong, 2-2. 5mm. long, obtuse, castaneous, the mar- 

 gins hyaline; bristles 4-5, exceeding the achene; achenes ellip- 

 sodial, pale, 1mm. long, the tubercle calyptrate, obscurely 

 broadened at base, about one-fourth as long as the achene. 



By stream banks in the Desert region. Palm^ Springs

 slope of Walker Pass, Kern Co., 3,900 ft. alt., 1014 Coville and

-! — ^Sheaths somewhat obliquely truncate ; tuber cule continuous 

 with the achene, seperable at maturity. 



/?. Eleocharis rostellata, Torr. Fl. N. Y. 2:347. 



Culms slender and wiry, lax, 3-5m. long, the sterile 

 culms 1-1. 5m. long, rooting at the apex ; spikelets oblong, acute, 

 1cm; long, and a third as thick, 10-20 flowered; scales ovate 

 to ovate-oblong, stramineous or light brown, bristles 4-6, ex- 

 ceeding the oblong-obvoid (1.5mm.) achene; tubercle conic- 

 subulate, less than one-half as long as the achene. 



Probably common in wet meadows throughout the Cis- 

 montane region, but the only specimens seen are of my own 

 collecting at San Bernardino. The species is found through- 

 out temperate North America.
