and stouter, but quite distinct by characters of pubescence, 

 flower and fruit.

 of the rhizome, mostly 8 or 10 inches high and monoce- 

 phalous, each with about 3 pairs of small leaves, the petioles 

 of these and also the stem and peduncles loosely villous and 

 somewhat viscid : lowest leaves subcordate-ovate, remotely 

 and often repandly dentate, the cauline with rhombic-lance- 

 olate acute blade 1 to 1J inches long, the lower ones peti- 

 olate, the upper sessile : involucre narrow-cam panulate, more 

 than J inch high, its lanceolate bracts viscid-pubescent: 

 rays large, golden-yellow, deeply tridendate: slender achenes 

 with short scattered bristly hairs and many minute dots; 

 pappus clear white. 



Marshall Pass, at 10,000 ft., 19 July, n. 515. Related to 

 A. cordifolia, much like it as to flower and fruit, but of dif- 

 ferent habit and foliage.

 tbe solitary stem 2 or 3 feet high from a fascicle of small 

 fusiform tuberous roots, glabrous or sparsely pubescent, glau- 

 cescent : leaves opposite, narrowly and acuminately lance- 

 olate, remotely and lightly serrate, triple-nerved below the 

 middle, scabrous on both faces with short pustulate acute 

 hairs, 3 to 6 inches long, on petioles of an inch or less : 

 heads 1 to 3, the broadly campanulate involucre of lance- 

 olate and subulate mostly appressed bracts strigose-pubes- 

 cent and ciliate: achenes oblong, glabrous, about 2J lines 

 long, the ovate-acuminate lacerate-toothed palea3 more than 

 half as long.
