SVNGENESIA ^QUALIS. 



632. Mich. 2. p. 95. Pursh, 2. p. 511. Nutt. 2. 



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. Floivers in a very large terminal corymb. 

 Involucruin loosely hemispherical; scales ovate-lanceolate, terminating in a 

 lone- 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.

Chrysocoma Tomentosa ? VValt. 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 inclies 

 long, scarcely one wide : densely tomentose underneath. Flowers in i ternn- 

 nal corymb. Scales of the involucrum ovate lanceolate, haiiy, termmating 

 in a very long filiform point. Corolla purple. . . 



This plant, of which however, my specunens are imperfect, contaming 

 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 Julv — August.
