 distinct from, C. jlava. Fertile spikes smaller. Fr. much 

 smaller than those of C Jtava, more in number, -with a shorter 

 and narrower-based beak which is conical when young. Very- 

 variable in height.— Bogs. P. VI. VII. E. S. I. 



55. C. exten'sa (Good.) ; fertile spikes oblong near together 

 subsessile lower one rather distant with a short included stalk, 

 bracts very long leaflike with short sheaths, gl. mucronate, fr. 

 ovoid triquetrous ribbed narrowed into a straight smooth-edged 

 Ijfid beak, nut oUong-elliptic triangular smooth. — E. S. 833. 

 Schk. V. Xx. 72. H. b. 32. R. 274:.St. usually curved, 8—12 

 in. high, trigonous, smooth, usually exceeding the leaves. Barren 

 spike nearly sessile, blunt ; gl. blunt. L. andhracts very narrow, 

 convolute, long. — Marshes, chiefly near the sea. P. VI. E.S.I. 



56. C. Hornschuchidna (Hoppe) ; fertile spikes ovate-oblong 

 distant with stalks exceeding the long sheaths, glumes ovate not 



. mucronate,/*-. ovoid triquetrous rough-edged also scarious in the 

 notch, nut obovoid trigonous nearly smooth. — H. b. 40. S. 352. 

 0. speirostachya (Sm.,^, B. 8. 2770. — Rootstock often creeping. 

 St. trigonous, rough-edged, about a foot high. Lowest bract 

 often reaching up to or beyond the barren spike. — Boggy places.

[C. xanthocarpa (Degl.) "has tufted stems, ovate-acute glumes, 

 spreading fr. not . scarious in the notch." It is said to be not 

 uncommon. I do not know it. — C.fulva Good., Sm., was an 

 error.— See J. of B. xiv. 366.] 



57. C. punctata (Gaud.) ; fertile spikes erect cylindrical with 

 slightly exserted stalks particularly the lowest, bracts sheathing, 

 gl. ovate shortly awned, fr. spreading ovoid tumid obscurely 

 veined pellucidly punctate with a linear bidentate smooth beak, nut 

 ovoidr^homboidal narrowed at both ends triangular rough. — H. 

 b. 37. Kwae Riedg. 6. R. 261.— St. smooth, 1—2 feet high, 

 slender. Spikes distant or the iipper ones near ; stalks slightly 

 (the lowest often greatly) exserted, rough ; lowest gpike often 

 very distant, Gl. pale red with a broad green longitudinal 

 dorsal band. Fr. pale. Nut brown. Gl. of barren spike blunt. 

 — Marshy places near the sea. P. VI. E. S. I. 



58. C. dis'tam (L.) ; fertile spikes remote erect oblong, upper 

 with included stalks, bracts with sheaths, gl. mucronate, fr. 

 ascending ovoid trigonous equally and faintly ribbed pellucidly 

 punctate smooth, edges of the bifid narrow beak rough, nut 

 triquetrous roughish obovoid narrowed below. — E. B. 1234.
