SYNGENESIA SUPERFLUA. 
357 
culato, glabro, rarais 
virgatis; involucris im- 
bricatis. 
paniculate, glabrous, 
branches virgate; in- 
volucrum imbricate. 
Sp. pi. 3. p. 2050. Pursh, 2. p. 557. Nutt. 2. p. 158. 
Stem two to four feet high, with long slender branches, slightly pubes- 
cent. Leaves sessile, narrow, lanceolate, serrate, glabrous; those of the 
branches entire. Flowers small, in racemes at the end of the virgate bran- 
ches, on peduncles two to four lines long. Scales of the involucrum linear- 
lanceolate, acute, nearly glabrous. Florets of the ray (sixteen to twenty,) 
narrow, pale purple. Seeds somewhat pubescent. 
I know not whether my reference of this plant is correct. I have of it 
apparently two varieties, one with leaves longer and more acutely serrate 
than the other and with flowers somewhat longer; but in habit similar. 
Grows in damp soils, along ditches, swamps, &c. 
Flowers September — October.

Stem two to four feet high, with the summit and numerous branches 
pubescent. Leaves lanceolate, very acute, finely serrate, glabrous; the 
small ones on the branches as usual entire. Flowers in somewhat crowded 
racemes on the expanding branches on peduncles one to three lines long. 
Scales of the involucrum linear-lanceolate, imbricate, nearly glabrous. 
Florets of the ray white, tinged with purple. Seeds somewhat pubescent. 
Mr. Nuttall considers the A. Difiusus of Aiton, and the A. Pendulus, Ait. 
with long divaricate pendulous branches as only varieties of the present 
species. The last would appear from description to approach very’ nearly 
the A. Junceus of this sketch. If they should prove the same plant, they 
must I think be separated from A. Divergens. 
Grows in woods in moderately fertile soils 
Flowers September— October.
