SYN6ENESIA SUFERFLUA. 
30. Tradescanti. Lin. 
A. foliis lanceolatis, 
seyratis, sessilibus, gla- 
bris; ramis virgatis; in- 
volucris imbricatis; 
caule tereti, glabro. 
Leaves lanceolate, 
serrate, sessile, gla- 
brous; branches vir- 
gate; involucrum im- 
bricate; stem terete, 
glabrous. 
Sp. pi. 3. p. 55 6. Mich. 2. p. 115. Pursh, 2. p. 556. Nutt. 2.p. 15&. 
Stem three to four feet high, glabrous, with numerous erect virgate bran- 
ches. Leaves lanceolate, acute at each end, when large finely serrate, when 
small entire, a little scabrous on the upper surface. Flowers small, in sim- 
ple or compound racemes, very numerous. Scales of the involucrum linear- 
lanceolate, acute, nearly glabrous. Florets of the ray, (about twenty) nar- 
row, pale purple, of the disk, yellow. Seeds a little hairy. 
The plant I have described agrees very exactly with the A. Vimineus, 
Willd: considered by Pursh, and I believe Mr. Nuttall, as a variety of A. 
Tradescanti. I must however remark that I have a specimen sent from 
Penn, by Dr. Muhlenberg, as the A. Tradescanti of Lin. which differs very 
widely from this, but differs, I think also, from the description of Ait. and 
Willdenow. 
Grows in the mountains of Carolina, Mich. Probably in all of the up- 
per districts, as it is found in the same range of country in N. Carolina. 
Flowers September— October. 
31. Discoideus. E. 
A? caule erecto sub 
villoso; foliis spathula- 
to ovatis, acutis, ser- 
ratis, pilosis, subtus 
pallidioribus; involucri 
squamis, subulatis, vil- 
losis, laxe appressis, 
sub squarrosis; radii 
corollulae 0. 
Stem erect, some- 
what villous; leaves 
spathulate, ovate, acute, 
serrate, hairy, pale on 
the under surface; 
scales of the involucrum 
subulate, villous, loose- 
ly appressed, some- 
what squarrose; florets 
of the ray none. 
Stem two to three feet high, erect, generally hairy, sometimes very vil- 
lous, branches not numerous, virgate, erect. Leaves all spathulate, distant- 
ly and coarsely serrate, very hairy on the under surface, three to four in- 
ches long, including the attenuated base, nearly two inches wide* Flower $
