the outer chaffy crown, is, however, very short and best seen in an early stage 
of growth. 
Chrysopsis hispida. Diplopappus hispidus, Hoox. Flor. Bor. Am., Vol. IL., 
p- 22.) In this ae so much allied to C. villosa, there are numerous aro- 
matic, resinous glands spread over most part of the plant; the quantity of this 
resinous matter, however, varies, but is never wholly wanting. The involu- 
crum is rarely at all smooth, more or less slenderly pilose, and sometimes glan- 
dular. Perennial, often somewhat decumbent, six to eight inches high, fasti- 
giately branched; the rays deep yellow, pappus brownish, scabrous. Radical 
‘leaves spathulate, long petiolate. Achenium silky. Outer short pappus chaffy, 
white, very distinct.—In C. villosa the outer pappus is far less distinct, and 
much more slender than in the present plant. 
Chrysopsis * foliosa; 2%, sericeously villous, and more or less canescent, the 
margin and lower surface of the leaves scabrous; flowers fastigiate, corymbose ; 
leaves entire, oblong or oblong-ovate, subamplexicaule, crowded, acute, ciliate 
below; scales of the involucrum linear, acute, villous; achenium — pappus 
scarcely scabrous, outer pappus slender, dimidiate. 
Has. In the Rocky Mountain plains, near the banks of the Platte. Flowering in August. 
About a foot high, sending up many hairy stems from the same root. Nearly allied to C. villosa, 
"put far more pubescent and hoary, with the leaves widest at the base. In some specimens quite 
hoary, the hairs feel as soft as silk, but on removing this clothing, the under surface is covered 
with numerous scabrous elevations. A very showy species. | 
Chrysopsts * mollis, 24; sericeously villous, leaves entire, spathulate-oblong, 
the lower narrowed below, the rest oblong and sessile, mostly obtuse; corymb 
few-flowered ; involucrum villous; the scales lanceolate, acute; achenium silky, 
the outer pappus minute. 
Has. With the above, which it much resembles, but the leaves are more — not in the least 
scabrous nor any where ciliate; the stem, also, a villous, 
§ 1. Subgenus. * PHyLiopappus.t Receptacle alveolate. Involucrum, sepals in 
about two series, subequal, flat. Outer pappus of about twenty paleaceous, 
linear-lanceolate, eroded scales, the inner of about twenty-five scabrous sete. 
Annual, mith the lower leaves incisely serrate. 
t From the exterior pappus being leaf-like.
