SYNGENES1A iEQUALIS. 
Willd. Sp. pi. 3. p. 1632. Mich. 2. p. 95. Pursh, 2. p. 511. Nutt. 2* 
p. 134. 
Root perennial. Stem five to six feet high, pubescent and branching to- 
wards the summit. Leaves numerous, long, narrow, lanceolate, a little sca- 
brous, nearly glabrous on the upper surface, finely pubescent, particularly 
along the veins, on the under. Flowers in a very large terminal corymb. 
Involucrum loosely hemispherical; scales ovate-lanceolate, terminating in a 
long, subulate point. Florets numerous. Corolla purple. Seed furrowed, a 
little hairy. Scales of the exterior pappus subulate, interior pappus long, 
hairy. 
Grows in ditches and wet lands. 
Flowers July— September. 
5. Tomentosa. E. 
Stem slender, to- 
mentose towards the 
summit; leaves long, 
narrow, lanceolate, ve- 
ry acutely serrate, 
slightly scabrous on 
the upper surface, to- 
mentose and hoary 
underneath; corymb 
fastigiate; scales of the 
involucrum filiform at 
the summit. 
Chrysocoma Tomentosa ? Walt. p. 196. 
Stem three to five feet high, rather slender for its height, finely tomentose, 
the summit and branches of the corymb hoary. Leaves five to seven inches 
long, scarcely one wide : densely tomentose underneath. Flowers in a termi- 
nal corymb. Scales of the involucrum ovate lanceolate, hairy, terminating 
in a very long filiform point. Corolla purple. 
This plant, of which however, my specimens are imperfect, containing 
only immature flowers, appears to differ from any of our described species, 
unless it be the C. Tomentosa of Walt. The filiform points of the involu- 
crum are twice as long as those of any other species that I have seen. 
Grows in wet soils, ditches. St. Thomas and St. Dennis, near Charles- 
ton, Mr. Caradeux. 
Flowers July— August. 
V. caule gracili, su- 
perne tomentoso; foliis 
longe angusteque lan- 
ceolatis, acutissime 
serratis, supra scabri- 
usculis, subtus tomen- 
tosis, canescentibus; 
corymbo fastigiato; 
involucri squamis api- 
ce fiiiformibus.
