150 BOTANY. 
ASTER ADSCENDENS, Lindl—Twin Lakes, Colorado, at 10,000 feet 
(522); also from Utah. Var. cruiatiro.ius, T. & G., stems with many linear 
leaves (1-3’ long and 1-3” wide), somewhat ciliate; scales of the involucre 
ciliate, acutish ; upper part of the stems rather hispidly pubescent.—Cotton- 
wood Creek, Colorado (524). The leaves are in the main narrower and 
the scales of the involucre less acute than in 252 of Hall and Harbour’s 
collection, with which my 509 more nearly compares. Number 492 of our 
Colorado collection is a slender, almost leafless state, with smaller rays and 
more acute tips to the involucre than the typical var. ciliatifolius. 523 ap- 
proaches A. falcatus, Lindl. Number 525, marked by Dr. Gray as a curious 
form, is, except for its smooth involucral scales, very much like A. integri- 
folius, Nutt. (No. 6166 of Bolander’s California collection), and so like the 
description of A. adscendens, var. Parryi, Eaton, that I am constrained to 
leave it there, and hence will probably be A. adscendens, Lindl. (?) (as con- 
sidered by Dr. Gray in Fl. Cal. 1, 324); from Colorado. A specimen of 
adscendens, however, collected by me at the Soda Spring, on Kern River, 
in California, is like 525 in the involucral scales, but with much narrower 
leaves. xcept this one from California and the one from Utah, all my 
material is from Colorado, at or above 10,000 feet altitude. 
: Aster Nurratuu, T. & G. Fl. 2, p. 126; var. Fenpvert, Torr. (A. 
. Fendleri, Gray, Pl. Fendl. p. 66).—In the absence of the plant, I subjoin 
the following original description of Dr. Gray, entire, from Pl. FendL.: 
“Span high, with many ascending, rigid, somewhat hispid stems from a 
subligneous root; branches monocephalous, corymbose-paniculate ; leaves 
small, rigid, entire, linear, coriaceous, sessile, mucronulate, smooth and 
single-nerved, with the margins hispidly ciliate; the lowest subspathulate, 
and the upper very short; involucre campanulate, scales in 3 series, linear- 
oblong, glandulose-scabrellate, mucronulate, the exterior herbaceous ones 
obtuse and lax, the interior a little longer, acute; achenia pubescent.” (510.) 
ASTER FALCATUS, Lindl_—Valley of the Upper Arkansas, Colorado, 
and San Francisco Mountains, Arizona (488, 501). 
ASTER sIMPLEX, Willd.—Nevada. 
ASTER MULTIFLORUS, L., var. y. commutatus, T. & G.—Stem slender, 
unbranched, nearly sessile, 3-4” in diameter; scales of the involucre
