* Chrysopsis Butleri sp. nov. 
Perennial; stem decumbent at the base or erect, grayish- 
hispidulous and slightly hirsute; leaves 1-3 cm. long, the lower 
obovate, the upper oblong or elliptic, obtuse or apiculate, often 
spreading, sessile, grayish-hirsute with short hairs ; heads pedun- 
cled but usually subtended by an oblong small leaf; involucres 8 
mm. high, 10-15 mm. broad; bracts linear, acute, hirsutulous, 
but not at all glandular or viscid; ligules about 8 mm. long; 
achenes silky-strigose ; pappus tawny, the outer of minute bristles. 
This species is characterized by the small, obovate or elliptic, 
subsessile leaves, which are often spreading and with short spread- 
ing pubescence. Nearly all the species of the Chrysopsis villosa 
group, with spreading pubescence, are more or less viscid or 
glandular, but this is not at all the case with C. Butleri. In leaf- 
form it resembles C. vz//osa, but both leaves and heads are smaller 
and the pubescence is different. In C. villosa the hairs are at 
least in the young state appressed.

liferous, apiculate ; heads corymbose, short-peduncled, rarely sub- 
tended by a small leaf; involucres 8 mm. high, 12-18 mm. broad ; 
bracts densely hirsute, only slightly granuliferous; rays golden 
yellow, about 1 cm. long; achenes strigose; pappus yellowish 
tawny, the outer of short bristles.
