Chrysopsis Brandegei. Low villous perennial, 3 to 5 inches 
high, with spreading branched scaly rootstock and numerous densely 
tufted stems: leaves spatulate, entire, gradually narrowed below into 
slender petioles, rounded at the summit but mucronate-acuminate at the 
very apex, l-nerved, finely grayish-pubescent and covered with very 
short yellowish glandular or resinous-tipped hairs (so short as to appear 
when viewed from above merely as sessile globules), and spreading-villous 
on the edges, 7 or 8 lines long including the petioles; lowest leaves 
shorter, densely crowded at the base, and often canescent with more 
appressed pubescence: peduncles terminal, slender, erect, flexuous, terete, 
1} to 2 inches long, villous with spreading hairs and also closely covered 
with the minute glandular hairs, entirely leafless but sometimes bearing 
one or two short filiform bracts: heads solitary, discoid, 6 to 8 lines in 
diameter, half inch in height, 40-45-flowered: scales of the involucre 
very unequal, imbricated in about 4 series; the outer ones very small, a 
line in length, very villous, the inner oblong, purplish, rather abruptly 
but acutely pointed, flat and smoothish, ciliolate on the margin, 3} lines 
long, half to two thirds line broad : corollas 5-toothed, golden yellow, gla- 
brous, 4 lines long : pappus manifestly double, the outer bristles very un-
