grosse serratis, utrin- 
que scabriusculis, longe 
petiolatis, membrana- 
ceis; involucri squamis 
lanceol'atis, ciliatis; flo- 
ribus parvis. E. 
ly serrate, a little sca- 
brous on both surfaces, 
on long petioles, mem- 
branaceous; scales of 
the involucrum lanceo- 
late, ciliate; flowers 
small. 
Root perennial. Stem about four feet high, terete, glabrous. Leaves 
large, opposite, on petioles two to three inches long, spathulate ovate, thin- 
ner than those of any other species with which I am acquainted, excepting 
those of H. Strumosus, slightly scabrous, not hairy on the upper surface, 
paler and a little pubescent on the under. Flowers few, small, terminal. 
Leaves of the involucrum lanceolate, fringed, appressed, as long as the disk. 
Florets of the ray about ten? yellow, about an inch long; of the disk not 
numerous. Seed obovate, compressed. Pappus subulate, pubescent. 
Chaff of the receptacle slightly tridentate, fringed at the summit and along 
the back. 
In structure and habit very similar to H. Spathulatus, but with thinner 
leaves, longer petioles, and smaller flowers. 
Grows in the western districts of Georgia. 
Flowers August — October.

Stem scabrous near 
the summit; leaves op- 
posite, spathulate-o- 
vate, slightly acumi- 
nate, serrate, scabrous 
on the upper surface, 
pubescent underneath; 
branches opposite; 
scales of the involu- 
crum lanceolate, hispid; 
chalf acuminate, entire. 
Root perennial. Stem four to six feet high, terete, striate, scabrous to- 
wards the summit, branches few, and in my specimens with the leaves always 
opposite. Leaves ovate, with long, tapering, slightly acuminated summits, 
as in almost every species triplinerved, abruptly attenuated at base into a 
petiole about half an inch long, pubescent and soft underneath. Flowers
