178 LEAFLETS. 



hasageographic form abundantin northern Colorado, many parts 

 of Wyoming and Montana ; another in Idaho (whence came the 

 original) and part of Montana, and throughout at least eastern 

 Washington and Oregon ; perhaps several rather than one. These 

 all have long calyx -segments and long narrow bractlets ; but 

 the foliage is different in different localities, though not very 

 definitely so. 



Var. OKNATA is marked essentially by its calyx-bractlets, 

 these being cleft into 2, 3, or 5 filiform segments. Specimens 

 are before me from Idaho (Heller), Washington (E. P. Sheldon), 

 and from the Yellowstone Park (Burglehaus). 



E. OAMPANULATA. Low, the stems 6 to 9 inches high, usually 

 2-flowered : leaves short, the leaflets crowded, obovate-cuneif orm 

 3 to 5-cleft, the lobes oblong, obtuse, upper face appressed-pilose, 

 margin not ciliate : flowers broad and short, quite campaualate, 

 with short deltoid-ovate segments and still shorter small bract- 

 lets hardly longer than the hemispherical tube, the whole greatly 

 surpassed by the obovate very obtuse crimson-tinted petals : 

 achenes not seen. 



Olympic Mountains, Washington, July, 1900, A. D. E. Elmer, 

 n. 2529 as in U. S. Herb. 



E. CANESCENS. Stouter than the last, sometimes taller ; leaves 

 as short, broader, canescently soft-villous and sparsely pilose ; 

 leaflets obovate-cuneate, with 3 to 5 segments or teeth mostly 

 broad, oval, obtuse but with small abrupt cusp-like termination : 

 stems mostly 3-flowered : calyx-tube very short, bractlets small, 

 commonly of but half the length of the ovate-lanceolate seg- 

 ments ; petals obovate-spatulate : plume hardly more than an 

 inch long. 



Northern Sierra Nevada, Calif., Brewer, 1863, on a volcanic 

 cone above Ebbett's Pass, 8,500 feet ; also from like elevation 

 above Donner Lake, Heller, 1903. Perhaps Cronkhite's n. 38 

 from Klamath Valley, and also Leiberg's n. 2555 from Steins' 

 Mountain, both these in Oregon, maybe referred here. 



E. QBiSBA. Caudex very large in proportion to the whole 

 plant ; stems at flowering only 5 to 8 inches high : foliage small, 

 firm, hoary with a quite uniform short villous-tomentose pubes.
