racemose rather large heads ; herbage, light-green and 

 flaccid, more or less pilose-pubescent, and at least the 

 upper parts of the plant glandular-viscid ; lowest leaves 

 spatulate-ovate and oblanceolate, obtuse, mucronulate, 

 entire, or with one or two pairs of crenate and mucronu- 

 late teeth below the apex, both faces sparsely pubescent 

 and the petioles as sparsely ciliate ; the cauline oblong- 

 lanceolate, entire ; heads three or four lines high, but 

 involucral bracts notably shorter than the flowers, 

 unequal, nearly linear, the inner acuminate, the tips of all 

 more or less spreading, the whole involucre as well as the 

 peduncles viscid-glandular, the basal parts hirsute- 

 pubescent ; rays apparently 60 to 80, not extremely 

 narrow ; pappus, copious and accrescent, dull white, little 

 darker in age. 



Distributed freely from the Herbarium of the Geological 

 Survey of Canada as E. acris, E. acris, var. Drcehachensis 

 and E. aljmius, to which species it was at various times 

 referred by Dr. Gray and Dr. Watson. Easily distin- 

 guished from E. Drcehachensis by its very different habit, 

 pubescence and inflorescence ; and the pappus of the latter, 

 at least in the American plant, becomes of a rich and 

 beautiful brown-red in age. The peduncles in the present 

 species, though slender, are abruptly and conspicuously 

 enlarged at summit under the involucre.
