ing suddenly very minute. Flotvers numerous, in racemes along the main 
branches, on small branches or peduncles about an inch long. Scales of the

Stem about two feet high, glabrous, somewhat sparingly branched. Leaves 
linear-lanceolate, acute, entire and slightly scabrous along the margin. 
Flowers at the summits of the branches, solitary, terminal. Scales of the 
involucrum linear-lanceolate, acute, loosely appressed, glabrous. Florets of

This species is by Mr. Nuttall considered as a variety of A. Tenuifolius, 
to which in its foliage it is closely allied. As I have specimens however
