of Africa. There are apparently none in New-IIoUand 

 and Northern Asia. 



48.FIMBR1STYLIS. 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. 1. F. puberulum. 2. castaneiim. o. cyUndricum, 



4. spudiceum. Ail species of Scirpiis of other authors, and 

 might probably with propriety rerrain so; as independent 

 of the very arbiti'ary and insufficient 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 sufiicient groundwork for a separate 

 section. 



49. RliYXCHOSPORA. VahU Schoenus. L. 



Scah^s of the calix collected into a spike^ 

 the inferior ones empty. Corolla 0. Base of 

 the stifle persistent. Involucellate filaments at 

 the base of the seed. 



This genus is well distinguished from Schcemis 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 mdurated as is 

 remarkabl) conspicuous in the R. lon^irostris. It appears, 

 also, that the nivolucellate filaments are always present.

50. SCHCENUS. L, and ValiL (Bog-rush.) 

 Scales of the calix collected into a spike, the 



inferior ones empty. Corolla 0. Stijle deci- 

 duous. 



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

 no involucelliite filaments.
