plicata, in apices ormes gradatim angustata, marginibus leviter sca- 
bridis. Spiculae 4-5; suprema mascula sessilis brevis pauciflora: ceterae 
omnino foemineae breves ovatae, quarum infima pl que remota pedun- 
longae foliaceae. Glumae ovatae acutae v. subacutae, pallide virides, 
tenues delicate pluri-nerviae. Utriculi 6-7 mm. longi, glumas subduplo 
superantes, anguste lanceolati, leves + plano-convexi glabri, leviter pluri- 
nervii, apice acuminato bifidi; styli rami 3; nux obtuse triqueter. 
A wide-spreading species forming a close continuous sward in swampy 
stations. ms numerous, 8-12 em. high, rather slender, stiffly erect, 
smooth striate, obtusely triquetrous (sometimes more or less compressed 
below), leafy to the middle. Leaves considerably longer than the culms, 
long-sheathing, grassy, 3mm. wide, flat or more or less complicate, 
many-nerved ; utricles 6-7 mm. long, about twice as long as the glumes, 
narrow-lanceolate, pale yellow, smooth plano-convex or nearly so, some- 
what compressed, faintly many-nerved, bifid at the acuminate tips; style 
branches 3; nut obtusely triquetrous.

This is a remarkably distinct plant, not closely related to any other 
native species. It fills considerable areas of swamp with a close grass-like 
sward, and never forms isolated tufts or tussocks. Mr. Carse’s specimens 
are in young flower; Mr. Morrison’s in ripe fruit.
