emerges a leafy bracted peduncle terminating in a single head. 

 There are about six foliaceons bracts on each peduncle, the low- 

 est three inches long, and the uppermost close to the head half 

 an inch long. Differing in these points from the then available 

 descriptions of H. algida, Professor Nelson and myself were led 

 to believe our plant to be a new species, and named it Hiilsea 

 caespitosa. 



The species was first collected by Brewer on Mt. Dana at 

 1 1500 feet, and by Bolander and Muir on the higher summits 

 of the Sierra Nevada mountains. Rothrock is reported to have 

 collected it on Ml. Whitney at 13700 feet. 



The collection from which our photograph was taken was 

 from the summit of Mt. Rose, Washoe county, Nevada, AVw;/^^^, 

 August 17, 1905. Other collections from the same place are 

 by Brown and Heller. These are the only collections from Ne- 

 vada that we know of at the present time.
