A FASCICLE OF NEW ARNICAS. 159 
A FASCICLE oF NEW ARNICAS, 
* Allies of A. CmawissoNis; stems tall, with few pairs of 
leaves, the radical ones wanting or inconspicuous. 
v A. CROCEA. Stout, 2 feet high, with 3 or 4 pairs of cauline 
leaves, and 1 to 3 long-peduncled large heads: lowest leaves 
oblong-lanceolate, short-petiolate, the cauline ovate-lance- 
olate, sessile by a broad base, sharply acuminate, obseurely 
denticulate, rather firm, slightly hoary-tomentulose on both 
faces; the stem and peduncles more hirsutulous, most of 
the hairs gland-tipped : heads $ inch high, 1 inch broad, 
almost hemispherical ; bracts of involucre biserial, narrowly 
lanceolate, acuminate, hirsutulous, not glandular: large 
orange rays 7-nerved, obtusely and not deeply 3-toothed ; 
disk-corollas with short villous tube and larger broad-funnel- 
form glabrous throat, the teeth with or without traces of 
bristles: achenes black, softly and rather sparsely hirsute ; 
pappus short, fuscous, subplumose 
This is well represented in n. 19, 645 of the Canadian 
Geol. Survey; the specimens collected by Mr. W. Spread- 
borough, at an altitude of about 5,800 feet on Canoe River, 
headwaters of the Columbia River, in British Columbia, 
11 Aug. 1898. By its large heads, with showy orange-col- 
ored rays, one would like to identify it with the very ill- 
defined A. mollis, Hook.; but the pubescence and the foliage 
are very far from answering to the little which Hooker had 
to say about them. 
, A. Conumprana. Dimensions of the last, but the heads 
more numerous and rather smaller; stem more leafy, all
