Var. i<A.Tiuscui<us. Pubescence and heads as in the type, 

 but monocephalous stems stout, rigidly erect, only 3 inches 

 high ; the tuft of basal leaves large in proportion, broader, 

 often very obtuse. 



This is from Twelve Mile Lake, Wood Mountain, in the 

 same province, and by the same collector. Its number is 

 10,894 of the Canad. Geol. Surv. 



Erigeron pachyrhizus. Low multicipitous subalpine 

 perennial, with something of the aspect of E. leiomerus as 

 to the parts above ground, but these tufted on the branches 

 of a thick woody-looking caudex, such branches ascending, 

 or nearly horizontal, dark with imbricated leaf -bases of many 

 seasons : IJ^ to 3 inches long, oblanceolate to spatulate-olong, 

 very obtuse, entire, of thin texture and bright green, sparsely 

 beset both superficially and marginally with setiform hairs, or 

 some of the lowest glabrous; stems several, subscapiform, 3 to 

 5 inches high, decumbent, bristly-hairy, usually monoce- 

 phalous, and with a few sessile small leaves ; involucre rather 

 narrow and subturbinate, its bracts almost uniserial, rather 

 few and broadly linear, acute, sparingly setulose ; rays short 

 and broad, perhaps white. 



Calapooia Mountains, Oregon, " on a bare peak, about a 

 mile west of the Cascade divide," Coville & Applegate, 9 

 Aug., 1897. Interesting plant, with some aflSnity for E. 

 leiomerus, yet doubtless also with points of contact with 

 alpine diminutives of E. calliantkemus . The color of the 

 herbage is unaltered by drying. 



Erigeron eucephaioides. Stems several, a foot high or 

 more, from a subligneous caudex crowning a thick hard root 

 or rootstock, loosely and rather equably leafy to the summit, 

 the bark whitish, smooth, glabrous, only the peduncles of the 

 1 to 3 heads scabrous-hispid ; leaves all eversrwhere glabrous 

 except as to the distinctly scabrous-ciliate margins, the basal 

 upright on long slender petioles, these and the narrowly
