364 SYNGENEStA SUPERFLtJA. 



Sp. p^3. p. 3035. Pursh, 2. p. 551. Nuttall, 2. p. 156, 



I insert this species with much hesitation; my specimens which were re- 

 ferred to.it by Dr. Muhlenberg, differ in some respects from the descrip- 

 tion of Wtlldenow, and may really belong to another section of this genus. 



Stem three to four feet high, striate, glabrous, branching very much to- 

 wards the summit, the young branches a Httle hairy. Root leaves wanting; 

 stem leaves spathulate-lanceolate, acute, or slightly acuminate, a little hairy, 

 particularly along the margins and veins. Fhwers small in compact clus- 

 tered racemes, forming a large terminal panicle. Scales of the involucrum 

 not very numerous, subulate, nearly glabrous. Florets of the tay about 

 twelve, narrow, pale purple; of the disk yellow, changing as they decay to 

 purple. Seeds very glabrous. 



This plant, which is probably the A. Paniculatus of Muhlenberg and 



Pursh. differs very essentially from the A. Diversifolius. The A. Panicu- 



latus of Nuttall, must certainly be a different plant. 



Grows in damp rich soils in the low country of Carolina. 

 Flowers September — October.

Sp. pi. 3. 2036. Mich. 2. p. 114. Pursh, 2. p. 552. Nutt. 2. p. 156. 



Stent two to three feet high, branching, the branches pubescent. Leaves 

 of the root and lower part of the stem cordate, tapering to an acute point, 

 acutely serrate, slightly pubescent underneath, on petioles one to two in- 

 ches long, very slightly winged. Flowers numerous, rather small, in pani- 

 cles composed of crowded racemes. Scales of the involucrum linear-lan- 

 ceolate, nearly glabrous, loosely appressed. Florets of the ray about 

 twelve, narrow, white, tinged with purple. Seeds glabrous. Varies, with 

 the lower leaves ovate-cordate, the upper spathulate-ovate, the serratures 

 nearly obtuse, and the petioles more conspicuously winged. 

 -Growls in the upper and mountainous districts of Carolina and Georgia. 



Flowers September-— November.
