442 North American Cyijeracect. 



Hab. Near New Orleans, T. Drummond ! 



Obs. This plant greatly resembles the ordinary form of 

 E. pygmaa, but the flowers are entirely destitute of bristles. 



E. PROLiFERA, p. 316. I have received specimens of this 

 plant, with mature fruit, collected by Dr. Chapman in 

 Middle Florida. It is a distinct species allied to E. micro- 

 carya. The spike is 4 — 6-flovvered ; the nut triangular, with 

 the sides convex ; the tubercle is broad, depressed, apiculate 

 in the centre. The bristles are about 4 in number, and scarcely 

 one-third the length of the nut.

 rence County, New-York, Dr. Crawe ! 



/3. brevifoliiis. Leaves much shorter than the culm, very 

 narrow, canaliculate, triquetrous towards the summit ; scales 

 shorter and scarcely acuminate. 



Culm a foot long, very slender. Leaves scarcely half a line 

 wide, 1 — 3 inches long, almost subulate. Spike broadly ovate. 



Hab. Ogdensburgh, N. York, Dr. Cravje. ! 



SciRPUS LENTicuLARis, p. 328. S. sylvaticus, Bong. ! 

 veg. Sitcha, in mem. acad. St. Petersb. 6 ser. 2. p. 169. The 

 specimen is young, but it agrees very well with Dr. Scou- 

 ler's plant. 



S. LiNEATUS, p. 332. District of Columbia, Dr. Crandall! 



Rhynchospora alba, p. 366. The Texan specimens of 

 Mr. Drummond, (Coll. II. no. 2S1,) are immature, and though 

 greatly resembling this species, may prove to be distinct; since 

 the hypogynous bristles are very numerous. I counted 19 in 

 some florets, and Mr. Arnott informs me that he has seen as 

 many as 24. The character of Rhynchospora must therefore 

 be slightly altered, so as to include this plant.
