Note on variation. — The various varieties which have been proposed, resting in part on previ- 

 ously published specific names, were originally segregated on several characters, but with the 

 accumulation of material these characters are seen to be inconstant. In the Sierra Nevada 

 one may find every intermediate from E. brevistylum to the form known as var. ursinum, while 

 the var. pringleanum is simply an extreme in the series, that is, a very slender state with narrow 

 leaves. Individuals representing var. pringleanum and var. tenue may be found in one narrow 

 colony, differing only slightly as to pubescence or the absence of it. Var. exaltatum is robust, 

 branching and large-flowered. 



Var. pringleanum Jepson. Low, 4 to 6 (or 12) inches high; herbage glabrous or sometimes 

 finely puberulent ; leaf -blades linear-oblong or linear-lanceolate, entire or inconspicuously denticu- 

 late, 1 to 3 lines wide, 6 to 11 lines long. — Wet soil, 5000 to 7000 feet: Sierra Nevada from 

 Tulare Co. to e. Siskiyou Co. ; Humboldt Co. to western Siskiyou Co. North to Washington.
