 bristles are present and are equal to or slightly shorter than the achenium, but in 

 this plant the bristles are entirely wanting. The same variation in this species has 

 been noted in other parts of the world.

 ity, "Agua Caliente, San Diego Co., Cal." 



On the west shore of Owens Lake (No. 999) and on the eastern slope of Walker 

 Pass (No. 1014). Our specimens show, as the type specimens did not, that the plant 

 is abundantly supplied with slender, creeping rootstocks. The plant has not been 

 reported since its first collection. No. 1014 was determined by Dr. N. L. Britton. 



Eleocharis rostellata Torr. Cyp. 318 (1836), under Scirpus; Torr. Fl. N. Y. ii. 347
