Stem slender, 15 inches - 2 feet high, the lower part often naked. Leaves 2-3 inches 

 long and about a line in breadth, oftea with smaller leaves fascicled in the axils, marked with 

 minute resinous dots. Heads smaller and less crowded than in the preceding species.

 is in general easily distinguished from the preceding by its narrow leaves and more slender

CHRYSOPSIS. 

 [From the Greek, chrysos, gold, and opsis, resemblance ; the prevailing color of the flowers being yellow.] 



Heads many-flowered : ray-flowers ligulate, pistillate, in a single series ; those of the disk 

 tubular, perfect, 5-toothed. Scales of the involucre linear, imbricate. Receptacle some- 

 what alveolate, flat. Branches of the style mostly terminated by linear hispid appendages, 

 often longer than the flat stigmatic portion. Achenia obovate or oblong-linear, compressed, 

 hairy. Pappus of the disk and ray similar, double ; the exterior short, somewhat chaffy 

 or setiform ; the interior of numerous rough capillary bristles. — Perennial plants, mostly 

 villous or silky, with oblong or linear usually entire leaves. Heads mostly corymbose, 

 showy. Flowers yellow. 



1. Chrysopsis falcata. Ell. (Plate LVI.) Sickle-leaved Chrysopsis. 



Stems assurgent, woolly ; leaves crowded, linear, mucronate, rigid, spreading or falcate, 

 about 3-nerved, hairy underneath, at length nearly smooth above ; heads (small) paniculate- 

 corymbed, the pedicels slender ; scales of the involucre villous ; achenia oblong-linear ; 

 exterior pappus setiform. — Ell. sk. 2. p. 336 (note); Beck, hot. p. 177; DC. prodr. 5.

 3 prominent longitudinal nerves. Heads 5 - 20, in a rather loose simple or compound corymb. 

 Involucre hemispherical ; the scales acute, somewhat carinate. Rays about 12. Pappus
