1 98 Monograph of North American Rhynchospora. 
Culms capillary, 6 — 12 (rarely 15) inches high. Leaves setaceous, 
shorter than the culm. Panicles sub-corymbose, nearly simple. 
Spikelets 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. 
Hab. S. Carolina and Georgia, Elliott and Dr. Baldwin ; 
Louisiana, Dr. Ingalls ; Middle Florida, Dr. Chapman. 
Obs. This plant was erroneously referred by Vahl, {Enum. 
I . p. 231.) to his R. niicrantha, 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 Sch(B- 
niis rarijlorus in Muhlenberg's Herbarium.
