A. Infirmus. Mich. 2. p. 109. 
Stem one to two feet high, pubescent. Leaves lanceolate, acuminate at 
each end, reticulately veined, very conspicuously hairy along the margins 
and veins. Flowers in small terminal corymbs. Scales of the involucrum 
lanceolate, a little hairy. Florets of the ray about eight, lanceolate, white. 
Seed glabrous. 
This species appears to me to differ from the A. Amygdalinus in its 
leaves, which are larger, .thinner, more reticulate, and more hairy, by its 
larger radial florets, and by its large glabrous seed. 
Grows in the mountains of Carolina. Pursh. Mich. 
Flowers September — October.

Stem about two feet high, striate, a little angled, finely pubescent near 
the summit. Leaves lanceolate, acuminate at each end, a little pubescent, 
the margin reticulately veined, but the veins not as prominent as in the 
preceding species, slightly scabrous on the upper surface. Flowers in a nu- 
merous and terminal corymb. Scales of the involucrum pubescent, scarce- 
ly longer than the mature seed, lanceolate, rather acute than obtuse } pubes-
