capitulis racemosis; in- 
voked squamis lineari 
lanceolatis, radio dimi- 
dio brevioribus. E. 
heads in racemes; 
scales of theinvolucrum 
linear-lanceolate, half 
as long as the ray. 
Stem four to five feet high, erect, very slender, with a few scattering 
branches, which near the summit become corymbose. Lower leaves four 
to six inches long, scarcely exceeding a line in width, very slightly scabrous 
along the margin, the upper diminishing in size; those of the branches linear- 
lanceolate. Flowers on the lower branches few, on the upper in racemes 
on peduncles two to four lines long. Scales of the involucrum linear-lan- 
ceolate, glabrous, loosely ap pressed. Florets of the ray about twenty, nar- 
row, twice as long as the involucrum, pale purple; of the disk yellowish-; 
Seed somewhat pubescent. 
Grows in damp soils in the western districts of Georgia. 
Flowers September — October.

Stem erect, two to three feet high, glabrous, with numerous expanding 
branches. Leaves one to four inches long, two to three lines wide, smooth, 
entire, somewhat appressed to the stem. Flowers very small, in a loose 
terminal panicle. Involucrum many leaved, imbricate, scales slightly re- 
flected at the summit. Florets of the ray about thirty, scarcely longer than 
the involucrum, unequally three-cleft, pale purple; of the disk, six to ten, 
yellow. Seeds hairy. 
Grows with A. Flexuosus in soils affected by salt water. 
Flowers September — October.
