SYNGENESIA FRUSTRANEA. 
in a loose, terminal, somewhat corymbose panicle. Leaves of the involu - 
crum ovate-lanceolate, small, much shorter than the receptacle. Florets of 
the ray about six, yellow, obovate, three-toothed; of the disk numerous, yel- 
lowish. Seed four-angled, crowned with a crenate margin. Chaff of the 
receptacle obtuse, tomentose at the summit. 
This species such as I have described it, grows abundantly in the western 
districts of Georgia. In a specimen of this plant sent me by Dr. Muhlen- 
berg from Pennsylvania, the segments of the lower leaves are all entire, 
smaller and but slightly acuminate. Do they belong really to the same 
species? 
Flowers August — October.

Root perennial. Stem four to five feet high, branching, somewhat sca- 
brous, and hairy. Lower leaves deeply three-parted, the middle segment 
large, lanceolate, serrate, a little hairy; the lateral segments nearly entire; the 
base attenuated and very hairy; upper leaves lanceolate, serrate, sessile. 
Flowers numerous, on the summits of the branches. Leaves of the involu - 
crum linear-lanceolate, reflected, about half as long as the rays. Florets of 
the ray about eight, lanceolate, deflexed, yellow, the base and exterior sur- 
face becoming deep orange when dry; of the disk numerous, dark purple. 
Seed four-angledj crowned with a four-toothed margin. Receptacle conic, 
chafflanceolate, acuminate, longer than the seeds. 
Grows in the mountains of Carolina and Georgia. Saluda mountains,
