 lindrical, blunt ; gl. blunt. Fertile spikes usually near together 

 and near the barren spike, sometimes distant ; gl. with a green 

 midrib slightly rough and often excurrent at the end. Beak of 

 the fr. curved downwards parallel-sided when young 1 . Lowest 

 fr. declining. 1 /3. C. lepidocarpa (Tausch !) ; barren spikes usually

57. C. (E'deri (Retz.) ; fertile spikes roundish-ovate subsessile 

 near together, lowest spike with an included stalk, bracts leaflike 

 with short sheaths, gl. mucronate, fr. subglobose inflated ribbed 

 smooth suddenly contracted into an erect narrow rough-edged 

 bifid beak, nut obo void-trigonous punctate, st. trigonous smooth. 

 Sy. E. B. 1074. //. b. 23. R. 272. Much like, but 

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

 smaller than those of C. flava, more in number, with a shorter 

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

 variable in height. [Var. cedocarpa (And.) has st. recurved, male sp. 

 stalked, fertile spikes distant, fr. more beaked.] Bogs. P. VI. VII.

58. C. exterisa (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 

 bifid beak, nut oblong-elliptic triangular smooth. E. B. 833. 

 Schk. V. Xx. 72. H. b. 32. R. 274. ?. usually curved, 812 

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

 spike nearly sessile, blunt ; gl. blunt. L. and bracts very narrow, 



1 Mr. Townsend (J. of B. xix. 1881, p. 161) discriminates the following 

 forms 



" a. genuina. L. shorter than the st., male spike nearly or quite sessile, 

 "female spikes contiguous, lowest bract much exceeding male spike; fr. 

 <; considerably narrowed towards the base, and gradually narrowing above 

 " into a much dellexed beak, which is as long as the rest of the fr. 



"$. C. lepidocarpa, Tausch. St. scabrous; 1. narrow, shorter than the 

 " st. ; male spike long-stalked, female spikes distant, ovate ; fr. crowded, 

 " suborbicular, beak long, strongly deflexed. 



" y. minor. St. shorter than in var. a ; 1. commonly as long as or even 

 " longer than the st., male spike usually stalked, female spikes usually 

 " distant ; fr. smaller, suborbicular, more suddenly contracted into a less 

 "deflexed or straight beak, which is shorter than the rest of the fr. 



" d. argillacea. L. broad, as long as or longer than the st. ; male spike 

 " short sessile, female spikes contiguous ; fr. suborbicular, beak short, 

 " straight." H. & J. G.
