352 SYNGENESIA SUPERFLUA. 



Sp. pL 3. p- 2032. Mich. 2. p. 113. Pursli, 2. p. 549. Nutt. 2. p. 156- 



Stem three to four or six feet high, with diffuse spreading branches, hairy ^^ 

 almost hispid. Leaves long, narrow, lanceolate, very entire, hairy and 

 sx5«ibrous along the margin, slightly auriculate at base. Flowers in a loose, 

 terminal panicle on small branches half an hich to three inches long. Scales 

 of the involucrum lanceolate, acute, somewhat hispid, scarcely longer than the 

 disk, frequently coloured. Florets of the ray numerous, narrow, bright 

 purple. Seefls hairy, almost villous- 



The plnnt I have described and which I collected in the western districts 

 of Georgia, belongs to the var. Spurius, A. Spurius. Willd. — but its bran- 

 ches are more difl'use, and its flowers more scattered than I believe are com- 

 mon in that variety. 



Grows in rich soils, sometimes to the heiglit of ten feet. Pursh. 

 Flowers Septcjuber — October.

Pursh, 2. p. 550? Nutt. 2. p. 156. 



Stem two to three inches high, glahrous or slightly pubescent on the 

 young branches. Leaves lineai-lanceoIate, those of the stem rather linear- 

 subulate, somewhat scabrous, very acute, slightly atnplexicaiJe. Flowers 

 scattered along rigidly expanding paniculate branches, on small branches or 

 peduncles half an inch to three inches long, not laige. Scales of the involo- 

 crum linear-lanceolate, nearly glabrous, loosely appressed, nearlyas longasthe 

 disk. Flor€t& of the ray numerous (twenty to twenty-four) narrow^ purple, 

 of the disk purple. Seed pubescent^ 



J have inserted this species whh much hesitation. I have no opportuni- 

 ty of referring to the figure of Hoffman as the type of this species, and the 

 plant I liavc^ described which was sent me undeV this* name by Dr. Schwei- 

 nitz is certainly not the plant of Pursh. It however differs from anj'^ spe- 

 cies I have hitherto described^ and until a pood monograph of this ijenus 

 with plates, shall be publ^^hed, many of its species must continue obscure 

 and doubtful.
