Culms 'capillary, 6—12 (rarely 15) inches high. Leaves setaceous, 

 shorter than the culm. Panicles snb-corymbose, nearly simple. 

 Spihelets few, (3 — 8) ovate, all pedicelled. Glumes ovate, mucro- 

 nate, fuscous. Bristles 6, very fragile so that the whole number is 

 seldom seen when the fruit is mature, minutely hispid upward, va- 

 riable in length, but always shorter than the nut. Stamens 3. Style 

 bifid. Nut obovate, deeply rugose, crowned with a compressed conic 

 tubercle scarcely half the length of the nut.

Obs. This plant was erroneously referred by Valil, [Enum. 

 I . p. 231.) to his R. micrantha, from the West Indies, a 

 species nearly allied to ours, but which differs in the length 

 of its bristles and tubercle. There is no specimen of Schce- 

 nus rarijloriis in Muhlenberg's Herbarium.

R. culmo triquetro, folioso ; paniculis axillaribus terminali- 

 busque, rarais divergentibus, laxe multifloris ; spiculis turgi- 

 do-ovatis, omnibus pedicellatis ; nuce globuloso-obovata, 

 transversim rugulosa, setis sursum hispidulis ^ breviore ;
