 feet, Hall and Babcock 3545 (co-type) ; same locality, 8,700 feet. Smiley 

 845; Lambert's Rock, Tuolumne meadows, Dudley, July 21, 1901. 



The characters relied upon to distinguish this segregate are cer- 

 tainly not of specific grade, unless every depauperate form is to be 

 considered as a species ; the character of narrower calyx-lobes than is 

 present in the type is wholly unreal when any considerable series is 

 examined ; but the vegetative aspect of the plant is sufficiently different 

 from that of the species to possibly warrant its maintenance as a 

 variety of ecologic significance.
