 Oreohrama Leana Howell, Erythea, vol. 1, p. 31. 1893. 



Type locah'ty. — "On the Siskij-ou Mountains, near the southern 

 boundary of Oregon." L. W. Lee. 



Range. — Siskiyou and Salmon Mountains, northwestern Califor- 

 nia, and southern Sierra Nevada. 



Zone. — Canadian. 



Specimens examinee!. — Woodehuek Peak, Fresno County, west 

 slope, 10-11,000 feet, among the first tamarack pines and also above 

 them, G. Eisen; Bald Mountain, Fresno County, 9,000 feet. Hall and 

 Chandler, 398. 



A plant collected by Congd'On on the Hennessey trail, Mariposa 

 County, is referred here by Dr. Jepson (Fl. Calif., vol. 1, pt. V, p. 

 477), but as represented in U. C. shows some characters unlike Leana, 

 as described and presented in the specimens of that species seen by 

 me; in jny opinion Congdon's plant is certainly not referable to the 

 type form of L. Leana, and is either L. cotyledon Robinson (a species 

 certainly known only from northwestern California) or is an un- 

 described plant; unfortunately the specimen is too fragmentary for 

 critical examination.
