A FASCICLE OF NEW ARNICAS. 173 
set of Flodman’s plants. It has been mistaken for a form of 
A. cordifolia, from which species it recedes in its very large 
cauline and small radical leaves, the absence of all pubes- 
cence, relatively small and always solitary head, and in some 
minor points. In a large-leaved plant like this, and from 
that region, one would liketo recognize the long suppressed 
A. macrophylla, Nutt. But our plant is far from answering 
the description of that species; which after all is perhaps a 
mere synonym of A. cordifolia, Hook., a species which, how- 
ever, neither Nuttall nor any one else could ever identify 
from Hooker's character of it. 
A. sUBCORDATA. Less than a foot high, the elongated 
monocephalous peduncle longer than the leafy stem ; both 
stem and peduncle strongly striate, and, with the petioles 
of the leaves, sparingly villous-hirsute: leaves ovate and 
ovaté-cordate, coarsely serrate or toothed, the largest 14 
inches long, on petioles as long, both faces rather sparingly 
and minutely pubescent; the reduced uppermost part del- 
toid-ovate, cuneate at base and sessile, entire: involucres 
large for the plant, fully $ inch high, the lance-linear 
acuminate bracts scarcely biserial, more or less villous-hairy 
and minutely glandular: rays light-yellow, long and nar- 
row, 3 to 5-nerved, apparently acute and usually quite entire 
at tip: achenes hirsutulous and puncticulate; pappus very 
fine and white, merely serrulate-scabrous. 
An exceedingly well marked small species, allied to A. 
cordifolia, obtained in 1898, by Mr. W. Spreadborough, on 
the Athabasca River. Itis in the Canadian Survey Her- 
barium, and in that of the Catholic University, under the 
number 19,644. 
A. vENTORUM. Size and habit of A. cordifolia, more 
slender, with thin and delicate glabrous foliage : radical
