A FASCICLE OF NEW. ARNICAS. 161 
Near Comax, Vancouver Island, 1 July, 1893, John Ma- 
coun. Distributed from the Canadian Survey Herbarium 
as A. Chamissonis, but the plant is more allied to A. 
amplexicaulis. 
V A. ovata. A foot high or more, stoutish, sparingly 
leafy, the leaves in only 2 or3 pairs and not more than 
half the length of the internodes, rather narrowly ovate, or 
lance-ovate, acutish, callous-denticulate, the lowest on short 
winged petioles, all finely pubescent on both faces, especially 
near and on the margin: heads about 3, subtended by a 
pair of ovate-lanceolate very acute bracts, the peduncles 
naked: involucres campanulate, their bracts lanceolate, 
acuminate, glandular-pubescent: rays rather narrow, mostly 
2-dentate; disk-corollas with very short hirsutulous tube 
and twice longer narrow-funnelform throat including the 
elongated-triangular naked teeth. 
Waksatch Mountains, Utah, at 11,000 feet, 31 July, 1879, 
Marcus Jones (n. 1,128 in my set); distributed for A. mollis. 
A. MACILENTA. About 2 feet high, with 5 or 6 pairs of 
rather ample thin leaves, the lower pairs elliptic-lanceolate, 
strongly connate-sheathing, the middle pairs lanceolate and 
oblong-lanceolate, sessile by a short spatulate base, the 
uppermost sessile by a broad half-clasping base, all obscurely 
dentate or entire, green and glabrous to the unaided eye, a 
lens disclosing a sparse indument of short bristly appressed 
hairs on the upper face, and of more slender and somewhat 
woolly ones beneath; stem and petiolar sheaths hirsutulous 
with white more or less retrorse hairs: heads about 3, on 
short slender peduncles; involuere campanulate, of 2 series 
of very thin oblong and oblong-lanceolate obtuse bracts 
somewhat appressed-villous with fine but obviously jointed 
hairs: rays thin, broad, obtuse, shallowly 3-dentate : disk-
