Eefs. — Jamesia Americana T. & G. Fl. 1:593 (1840), type loc. Eocky Mts. of Colo., James; 

 Engler in Engler & Prantl, Nat. Pflzf. S^":?:, fig. 36H-M (1890). Var. californica Jepson, 

 Man. 466 (1925). Edwinia californica Small, N. Am. Fl. 22:176 (1905), type loc. Volcano Creek 

 Falls, near Kern Canon, Tulare Co., Eastwood. Small's character for the Californian shrub, 

 "Sepals obtuse or retuse; leaf -blades few-toothed, dentate", does not apply, but his character 

 for the Eocky Mt. shrub, "Sepals acute; leaf-blades many-toothed, serrate", applies well to the 

 Sierra Nevada form. The flowers of our form are, however, pink, while those of the Colorado 

 shrub are white.
