Anisocoma acaulis Gray, Bost. Journ. Nat. Hist. v. Ill (1845). Type locality

The achenia in our specimens are often 14-nerved. This is a beautiful plant in all 

 its parts and deserves a trial in cultivation. It may be noted here that the generic 

 name is feminine and the specific name should read acaulis, as originally published, 

 not "acaulc," as in the Botany of California and the Synoptical Flora; and that the 

 genus and species were published by Gray, not by Torrey and Gray. 



This beautiful annual' was seen but sparingly, occurring in the upper part of the 

 Lower Sonoran zone. It was found only in Willow Creek Canon, Panamint Moun- 

 tains (No. 749), and near Crystal Spring, Coso Mountains.
