Dr. Gray, in describing the var. alpina, clearly recognized its 

 doubtful character, as distinct from C. nevade'fisis, and the collections 

 made since demonstrate the impossibility of maintaining it apart from 

 the latter species. The extension of the range of the species to Wash- 

 ington is based upon Professor Piper's identification of Brandegee 

 906 from ]\It. Stuart ; this collection is the only one reported nortli of 

 the southern Cascades. 



The reference to the synonjTny of C. nevadensis of C. Dougl-asii 

 var. mantana Jones is based upon description only. If there are 

 plants within the Sierra, which justify the segregation, they have not 

 come to my notice. This variety is said by its author to include 

 "most of the forms usually referred to the var. alpinu of Gray. . . . 

 This is the usual form of the higher mountains, from 7,000 ft. to 9,000 

 ft. alt., and ranges from the Rocky Mountains of Colorado to the 

 Sierras." It is referred by Rydberg (N. Am. Fl., vol. 34, p. 72) to the 

 synonymy of C. pedncularia Greene (by error called ^'pedunculari-a"), 

 a species described (Pitt., vol. 4, p. 98. 1899) from the mountains 

 of southern Colorado and considered by Professor Aven Nelson ( Coul- 

 ter-Nelson New Manual, p. 557) to be indistinguishable from the var. 

 alpina Gray.
