48.FIxMBRlSTYLIS. Vahl Scirpus. L. (Club- 

 Rush,) 



Scales of the calix on all sides imbricated 

 in a spike. Corolla 0. Style ciliate, decidu- 

 ous, and bulbous at the base. (Seed generally 

 destitute of involucellate filaments.) 



Species. I. F. piiberiihim. 2. castaneum. 2. cylindncnm. 

 4. spadiceum. All species of Scirpus of other authors, and 

 might probably witii propriety remain so; as independent 

 efthe very arbitrary and insuincient character of this ge- 

 nus, if such it can be called, there is not even the advan- 

 tage of any peculiar habit, that should indicate the ne- 

 cessity of such a separation. The ciliation of the style 

 appears to be the only discriminative character, a cir- 

 cumstance, which upon other occasions would scarcely 

 be considered as a sufficient groundwork for a separate 

 section. 



49. RHYNCHOSPORA. Vahl. Schcexus. L, 



Scales of the calix collected into a spike, 

 the inferior ones empty. Corolla 0. Base of 

 the style persistent. Involucellate filaments at 

 the base of the seed. 



This genus is well distinguished from Schcenus by the 

 persistent base of the style, often in the form of an acu- 

 minated conic tubercle/and in some instances the whole 

 style remains, becoming enlarged and indurated as is 

 remarkably conspicuous in the R. long-irostris. It appears, 

 also, that the involucellate filaments are always present.

50. SCHGENUS. L. and Vahl (Bog-rush.) 

 Scales of the calix collected into a spike, the 



inferior ones empty. Corolla 0. Style deci- 

 duous. 



In this genus, as it now stands, it appears that there are 

 WLinvoiuceUate filaments.
