CYrERACEiE. 75 



leaves in the lower half; the upiier shoath with a very short subulate 

 triquetrous lamina nmcli shorter than its sheath. Spikes solitary, 

 few, shortly stalked and sessile, in a simple umbellate corymb, 

 obconical-obovate and subobtuse at the apex in fruit. Peduncles 

 scabrous-puberulent, erect or inclined. Bracts unequal, the lowest 

 one connnonly with a short foliaceous point, considerably shorter 

 than the longest peduncle. Glumes ovate-lanceolate, with subobtuse 

 triangular points, blackish-olive, with i)ale midribs, without white 

 scarious margins and apex. Hypogynous bi'istles very numerous, in 

 fruit straight and five or six times as long as the glumes.' Nut 

 narrowly oblanceolate, rounded, not mucronate, compressed-trigonous. 

 In bogs. Very i-are. Whitemoor Pond, halfway between Guildford 

 and Woking, Surrey; Ilalnaby, Yorkshire, in a strip of boggy ground 

 on the left-hand side of the road from Croft, discovered by J. Woods 

 in 1835, and authenticated by W. Borrer in 1854. 



England. Perennial. Early Summer. 



Much more slender than E. angustifolium, and with the stems dis- 

 tinctly trigonous, 1 to 2 feet high. Radical leaves much narrower; 

 stem leaves very short, the upper ones with a lamina ^ to 1 inch long, 

 and with much longer sheaths. Spikes fewer, more unequally stalked, 

 fewer-flowered and much smaller, i inch long in flower, 1 to 1;^ inch 

 in fruit. Glumes much less triangular and blunter, greener, and 

 wthout evident scarious margins. Nut smaller and narrower, more 

 obtuse at the apex, and without a distinct mucro. Bristles absolutely 

 shorter, but longer in proportion to the glumes and nut. 



Of this plant 1 have never seen recent specimens.

Cajspitose. Rootstock very shortly creeping, producing tufts of 

 radical leaves and flowering stems. Radical leaves linear, flat, keeled, 

 triangular for only a short distance at the apex. Stems rather stout, 

 bluntly trigonous throughout, more decidedly so towards the apex 

 hollow, with two or three leaves in the lower two-thirds, with 

 the lamina? broadly linear, flat, with a short triangular point, tlio
