420 North American Cyperacea. 
in the axil of a setaceous bract; the others on partially enclosed pe-. 
duncles. Fruit, ovate, inflated, grarkially tapering into a beak, beauti- 
fully striate. NuL triquetrous, with very concave sides. 
Obs. This species has the habit and general aspect of C. 
follicidata, Linn., from \^hich it seems well distinguished by 
the inflatad fruit with regular and prominent striae ; the nar- 
rower more rigid and scabrous leaves, &c. We suspect that 
it will prove to be the C.follicuUita of Elliott.
