Type specimen, Butler 1205, Oro Fino, Siskiyou Co., in damp shady woods, 

 Apr. 2.1, 1910. The only other specimens seen from California are Butler 1206

 occurs in Idaho (Beaver Canon, Shear 297). The above description is drawn 

 from the type specimen in the National Herbarium.

 species includes a number of rather diverse forms which with our present knowl- 

 edge can not be satisfactorily separated into distinct species. The following 

 are some of the numbered specimens referred to this species : Abrams 1162, 1475, 

 3105, Bolander 1547, 1550, Brewer 233, 1024, 1122, Davy 6650, Hall 1439, 1661,
