540 Piper : Notes on Calochortus 



Letter g 575 ; Peshastin, Sandterg & Leiterg, July, 1893 ; " North 

 Branch of the Columbia," Wilkes Expedition 1068. 



Specimens collected by Cotton have kindly been compared for 

 me with the type of C. Lyallii by Mr. E. G. Baker, who states 

 that they differ only in the relative length of the anthers to fila- 

 ments. This character, however, varies with age. The species is 

 very distinct from C. elegans and its immediate allies in having 

 erect pods. It may readily be recognized by its narrow, acumi- 

 nate, jagged-margined petals which excepting the scale are glabrous 

 or only sparsely pilose, and by its abruptly subacute anthers. 

 Thus far the species has been found only in Chelan, Kittitas and 

 Yakima Counties, Washington. 



Calochortus elegans Pursh, Fl. Am. Sept. 240. 18 14. 



This is the type species of the genus and was collected by Lewis 

 "on the headwaters of the Kooskoosky, Idaho/' The exact lo- 

 cality was at Lewis and Clark's spring camp of 1806, opposite the 

 present site of Kamiah, Idaho. The species is common in pine 

 woods in the Bitter-Root Mountains of Idaho and the Blue Moun- 

 tains of Washington and Oregon up to 2000 meters altitude. It

varies considerably as do other species in the breadth of the solitary 

 leaf and in the size of the flowers. The smaller and larger forms 

 were long ago named by Hooker, in the Flora Boreali-americana, 

 C. elegans major and C. elegans minor, but these seem unworthy 

 of botanical recognition.
