210 LEAFLETS. 



these and tufts of larger leaves from a short branched crown 

 or caudex, the leaves to all appearance glabrous, but not so 

 the stem and long peduncles of the several large heads, these 

 sparsely but rather coarsely setose-hispid and striate ; basal 

 leaves on short broad petioles, these and narrowly oval or 

 spatulate-oblong blades 3 to 6 inches long, obtuse, entire ; 

 cauline leaves small, oblong, sessile, from 1 inch long in the 

 lower to % inch long in the upper, all glabrous except as to 

 the rather strongly and stiffly ciliolate margins ; heads corym- 



bose, the hemispherical involucres little more than % inch 

 high, twice as broad, the bracts equal, linear, strigose-his- 

 pidulous and most so near the margin, not at all granular ; 

 rays narrow, not excessively numerous, nearly % inch long, 

 apparently purplish. 



Known to me only as collected in the Mogollon Mountains, 

 New Mexico, by H. H. Rusby in 1881. 



A natural group of rather tall and leafy, mostly white-rayed 

 erigenus, of which E. Coulterixs an old and a good representa- 

 tive, has yet not a few unrecognized species ; among them the 

 following, from Oregon. 



Erigeron nemophilus. Large perennial, with stems 

 stoutish, simple and monocephalous, lY^ feet high, with a 

 copious investiture of large stem leaves ; basal foliage of an 

 elliptic-lanceolate blade and narrow petiole of nearly equal 

 length, the whole 3 inches long or more, entire, very acute, 

 the cauline almost as large, but sessile, broadly lanceolate, 

 with 1 to 3 salient serrate teeth on each margin, the texture 

 of all very thin, unaltered as to the deep-green color in dry- 

 ing, both faces sparsely hairy, the margins closely beset with 

 very different short incurved hairs ; stems sparsely hirsute 

 below, more thinly soft-strigose above the middle ; head very 

 large, the narrow and equal involucral bracts soft-hirsute at | 



and near the base, otherwise green and glabrous, with hardly 

 a perceptible trace of the glandular : rays numerous, not so 

 extremely narrow, apparently light rose-red.
