sparsely pubescent with whitish hairs, the radical narrowed into a very short 
hairy petiole ; heads not large ; involucral scales in two series, narrowly lan- 
ceolate, the outer greenish, hirsute, minutely glandular, the inner chartaceous 
with a dark midvein ; rays purple, about 50, twice longer than the involucre, 
about ¥' wide ; achenia hirsute ; pappus with minute bristles intermixed with 
the longer ones.— This species will come into Euerigeron, and should be

wool on the involucre, besides the other characters, distinguishes it. The
