ARNICA PEDUNCULATA.
Stem 3-6 dm. high, finely villous-pubescent, striate ; basal leaves broadly oblong to almost linear, entire, 3-ribbed, tapering into a more or less winged petiole ; stem leaves about 2 pairs, similar, but narrower and sessile ; head on a peduncle that is often dm. long ; bracts 18-20, linear or lanceolate, acute but not acuminate, villous-pubescent : disk 15-18 mm. high ; rays fully cm. long, orange ; achenes hirsute, pubescent.
It is somewhat between A. foliosa incana and A. a/pina in habit, but differs from both by the long-peduncled solitary head and finer pubescence. It was collected by J. H. Flodman in the Spanish Basin, July. II, no. S99 (broad leaved) and July 10, no. 900 (narrow leaved), 1896. Also collected in Idaho by A. A. & Gertrude Heller, no. 3293, 1896, and in Washington during the Wilkes expedition.
