164 PITTONIA. 
mostly 2 or 3, slender-peduncled; involucre about 3 lines 
high and 4 or 5 broad, the bracts equal, broad, not numer- 
ous, attenuate-acuminate: rays 25 or 30, broad and rather 
short, white. - 
Deer Creek Mountains, J osephine Co., Oregon, July, 1887, 
Mr. Howell; evidently subalpine and of moist if not marshy 
ground. Species singularly combining the characters of 
Aster andinus and Erigeron salsuginosus; and about as natu- 
rally referable to Aster as to Erigeron. 
ERIGERON ELATUS. E. alpinus, var. elatus, Hook. Fl. ii. 
18. Stems several, erect, from a perennial root, 6 to 18 
inches high, striate-angled, reddish and hirsutulous, only 
sparingly leafy except at base, bearing at summit eithera 
solitary rather large head, or 3 to 5, which are slender- 
peduncled and subcorymbose: lowest leaves from small and 
obovate with slender petiole, to narrowly and spatulately 
oblanceolate, obtuse, entire, glabrous beneath, above sparsely 
strigose, distinctly hirsute-ciliate, at least below the middle; 
the cauline linear-lanceolate to linear, sessile, acute: in- 
volucres 4 or 5 lines high and 6 in breadth, bracts linear- 
acuminate, almost hispidly short-hirsute, not glandular, un- 
equal, the outer little more than half the length of the inner: 
rays very numerous, elongated and manifestly spreading, 
bright pink or red-purple: pappus white, rather copious, 
somewhat accrescent. : 
Var. Bakert. Plant larger, glandular and viscid, desti- 
tute of other indument, except that the leaf margins are 
hispid-ciliolate: rays apparently fewer and broader, perhaps 
not spreading. | 
The type of this species, which is decidedly a handsome 
one for a member of the E. acris group, seems to be common 
in the mountains of British Columbia, where Mr. Macoun 
has repeatedly collected it. The variety is subalpine in the 
mountains of northern Colorado, having been collected at 
and near Cameron Pass, in 1896, by Mr. Carl F. Baker.
