densely villous below the middle: rays elongated, deep- 
yellow, 9-nerved, 3-toothed, the teeth short: disk-corollas 
short, the villous tube and glabrous short-cylindric throat

broad; stems low.

reniform-ovate, 2 inches in length and breadth, truncate or 
subcordate, on petioles of 1 or 2 inches; middle pair of ovate 
or lance-ovate outline, short-petioled and the petioles winged ; 
the floral pair reduced, triangular; all saliently and often 
coarsely serrate-toothed, glabrous beneath, the upper face 
sparingly pubescent and glandular, the stem and peduncles 
glandular-puberulent or pubescent: involucres only glan- 
dular-pubescent, their thin bracts lanceolate, acuminate:

On northward slopes of the highest Powder River Moun- 
tains, eastern Oregon, at 8,000 to 9,000 feet, W. C. Cusick,

reason; for the plant is of that group to which A. cordifolia 
belongs, rather than an ally of A. latifolia. 
A curowoPHiLA. Dwarf, usually 5 to 10 inches high, mo- 
nocephalous, and with but a single pair of cauline leaves, 
these inserted toward the base of the long naked peduncles;
