SYNGENESIA SUPERFLUA- 
Sp. pi. 3. p. 2060. Pursh, 2. p. 538. Nutt. 2. p. 159. 
Stem three to four feet high, villous, when young almost tomentose, bear- 
ing towards the summit many recurved branches. Leaves (of the root ob- 
ovate, Pursh,) of the stem oblong-lanceolate, acute, rarely acuminate, 
acutely serrate, veiny, slightly scabrous on the upper surface, hairy under- 
neath, particularly along the veins. Flowers in an oblong terminal panicle, 
the racemes secund and recurved. Scales of the involucrum oblong, nar- 
row, rather obtuse. Florets of the ray about seven, scarcely longer than 
the involucrum. Seeds pubescent, almost villous. 
In changing in some respects the character of this species given by Will- 
denow, I have been guided by specimens sent me by Dr. Muhlenberg him- 
self, with which plants collected in the western districts of Georgia exactly 
agree. 
Grows in rich shaded soils. 
Flowers September — October.

Sp. pi. 3. p. 2060. Pursh, 2. p. 538. Nutt. 2. p. 159. 
Stem two to three feet high, very glabrous, though sometimes a little 
pubescent on the young branches, striate, frequently coloured, the branches 
long, virgate. Leaves of the root spathulate ovate, very acutely serrate, the 
attenuated base t>vo to four inches long; of the stem oblong-lanceolate, ser- 
rate, of the branches lanceolate, entire, all glabrous, and somewhat tripli- 
nerved. Floivers on recurved racemes forming long terminal panicles. 
Scales of the involucrum, as in most of the species, linear-lanceolate, nearly 
glabrous. Florets of the ray of a middling size. Seeds minutely pubes^ 
cent. 
Grows in moderately rich, shaded soils. 
Flowers in September.
