Chrysopsis Linariifolia. Nutt. 2. p. 122. 
Stem about two feet high, generally erect, when young pubescent. 
Leaves alternate, but crowded, expanding or reflected, with the midrib very 
prominent, very scabrous along the margins, about an inch and half long. 
Flowers in an umbellate corymb, the branches generally one-flowered and 
clustered at the summit of the stem. Scales of the involucrum very nume- 
rous, imbricate, linear-lanceolate, fringed. Florets of the ray ten to twelve* 
linear-lanceolate, three-cleft at the summit, pale purple; of the disk nume- 
rous, yellow. Seeds oblong, villous. Pappus double or composed of short 
hairs intermingled with the long. 
Between the A. Rigidus of Pursh, and this species, I can perceive no dis- 
tinction. 
Grows in dry soils, very common. 
Flowers September— -November?
