Culm rather slender, 1 — 2 feet high, obtusely trigonous. Leaves narrow- 

 linear, flat ; the lower ones 4 — 6 inches in length ; the upper ones 

 shorter. Corymbs fascicled ; the (2 or 3) upper ones aggregated at 

 the summit of the culm; the lateral ones (1 or 2) distant, on short, 

 exsert peduncles. Spikelcts ovate. Glumes fuscous, broad-ovate, 

 mucronate.. Bristles 6, minutely hispid upward, about as long as the 

 nut. Nut smooth, broad-ovate, lenticular. Tubercle compressed- 

 conic, a little dilated at the base, one-third the length of the nut.

Culm somewhat acutely triangular. Corymbs rather loosely fasciculate, 

 the lower ones long-pedunculate. Bristles nearly twice the length of 

 the nut. Tubercle not dilated at the base.

 Obs. The synonyms of Vahl and Pursh are omitted, as it is 

 impossible to determine the plant to which they belong. 

 They may be referred with about an equal chance of cor- 

 rectness to R. glomerata, R. gracilenta, and the present 

 species. Var. /3, although differing in the above-mentioned 

 particulars, and uniformly having bristles longer than the 

 nut, is not, I think, specifically distinct.
