NEW OR NOTEWORTHY SPECIES. 103 
Very frequent in southern Colorado, at Cañon City, etc.; : 
evidently forming a part of Gray's G. squarrosa, var. nuda, 
though not at all the G. nuda of Wood. Ibis most certainly 
distinct from G. squarrosa not so much by its discoid heads 
as by its perennial root. Not only this but\also both the 
preceding new species have a persistent tap root surmounted 
by a central tuft of radical leaves, around which tuft the 
stems of each succeeding year are produced. G. squarrosa, 
as I have noted during many seasons, is always strictly bien- 
nial, the stem erect and terminal to the root-axis, the radical 
leaves dying as the plant approaches maturity, quite as in 
all biennials. Herbarium specimens usually fail tà show 
Ses things, hence much confusion in the herbaria and in 
ooks. WE 
ASTER OXYPHYLLUs. Rigidly erect, 1 to 2 feet high, from 
horizontal branched rootstocks, leafy up to the ample often 
corymbose panicle, nearly glabrous: leaves all lanceolate 
and linear-lanceolate, entire, acute, scabrous on the margins, 
the cauline sessile by a broad half-clasping base, the radical 
with short narrowly winged and ciliate petioles: the rigid 
ascending branches and branchlets of the panicle sparsely 
pubescent and subulate-bracted: involueres } inch high, 
much imbricated, the outer bracts green almost throughout, 
the inner with green tips, all densely ciliolate: rays about 
25 or 30, blue: achenes pubescent. 
On clayey banks and bottoms of the Grand River, at Grand 
Junction, Colorado, 26 Aug., 1896. 
ARNIcA SPATHULATA. A foot high or more, stoutish, 
somewhat viscidly hirsute and tomentulose, very leafy below, 
and floriferousfrom about midway of the stem: lowest leaves 
3 to 5 inches long, broadly lanceolate-spatulate, doubly 
toothed, the two or more pairs of lower cauline more nar- 
Towly spatulate but dilated just above the insertion: pedun- 
cles 6 to 10, the lowest with a pair of ovate-acuminate sessile 
bracts in the middle: heads campanulate, $ inch high; in-
