oblong, triangular, with a stout trigonous beak that projects be- 
yond the mouth of the perigynium. Smith has shown (E. FI. iv. 
p. 113) that C. montana L. is the same as C. pilulifera; and the name 
having been applied to several other species, it is preferable to adopt 
that given by Willdenow.

litary with acute glumes, fertile 1 — 3 subglobose approximate 
sessile, sheaths none, lowermost bractea subulate scarcely folia-

Moory ground, frequent. . 6. — Stems 6 — 12 inches high,

60. C. tomentosa L. ( larger downy -fruited Cl) ; glabrous,

Boggy marshes, rare; chiefly found in Scotland. Leicestershire; 
Shropshire; Suffolk. It . 5. — Stem 1 — 2 ft high. Leaves slender, 
I their margins involute, filamentose at their base near the roots. 
1 Closely allied to C. tomentosa, with which it was confounded by Light- 
foot and Hudson. 
62. C. hirta L. ( 'hairy C .) ; hairy, barren spikelets 2 — 3, fer-

gated, bracteas long foliaceous, glumes elliptic-lanceolate much 
acuminate ciliate towards the point, fruit hairy oblong-ovate 
with a long beak deeply bifid at the point. — a. lower sheaths
