Boott says the style is sometimes 3-fid; I find all 2-fid in Boott's exiunples; the 

 utricle is pressed so very flvit (as is the nut) that I am surprised to find a 3-fid 

 style even by accident. The name of Kunze has priority ; but, as bis description 

 may be esteemed insufficient, it is more convenient not to unearth his name. 



2. C. runssoroensis, K. Schum. in Engl. PJl. Ost-Afr. C. 129. 

 Stem terete, smooth with very many striations. Uppermost leaf f in. 

 long, not green. Utricle (witliout beak) \ in. long, oblong, much 

 flattened, with 6 nerves on the convex face, reddish, beak scarcely \ the 

 length of the utricle, otherwise as C. nionostachya.

This species is exceedingly near C. monostachya, A. Rich.; the one stem at Kew 

 appears almost a scape ; the utricle is less obovoid and much less beaked than the 

 utricle of any example of C. monostachya. A rudiment of the male spikelet is in 

 the utricle. 



3 . C. conferta, Hochst. ex A . Rich. Tent. Fl. A hyss. ii. 512. Glabrous. 

 Rhizome creeping, divided, up to 6 in. long in dried examples. Stems 

 1-3 ft. long, medium-sized, triquetrous, rough on the angles. Leaves 

 nearly as long as the stem, \ in. broad. Inflorescence 2 by ^ in., a 

 dense little-interrupted oblong panicle ; lowest bract shorter than the 

 panicle, often only J in. long, not sheathing. Spikes ^ by i in., dense, 

 female at the base, some male at the top. Female glumes ^^ in. long, 

 ovate-triangular, not acuminate, a rich brown, keel yellow. Utricle y^ in. 

 long, sessile, ovoid-triangular, hardly beaked, plano-convex, glabrous, 

 straw-yellow, without nerves on the plane face, obscurely 2-3-nerved 

 on the convex face ; beak deeply split on the convex face, margins 

 scabrous ; style-branches 2, linear.— Boott, Carex, ii. 76, t. 208 ; Boeck.

Compared by Boott with C. vulpina, Linn., of which it has the habit and 

 characters, but a less beaked and less ribbed utricle. It is equally nenr the corre- 

 sponding group in South America, of which C. hracteosa, Kunze, is a representative. 



4. C. leptosaccus, C. B. Clarke. Inflorescence ovoid, 21 by 

 1 in., dense, compound, straw -brown ; lowest bract as long as the 

 panicle. Spikes \-\ by i in., female at the base, a few male at the 

 top. Female glumes ~ in. long, elliptic- lanceolate, hardly mucronate, 

 ferrugineous, keel green. Utricle J in. long, hardly stalked, elliptic- 

 lanceolate, beaked, plano-convex, glabrous (a very few hairs on the 

 margins), white, very thin, without nerves on the plane face, obscurely 

 3-nerved on the convex face ; beak lanceolate, J-J the length of whole 

 utricle, deeply split on the convex face ; style-branches 2, linear very 

 long, brown-red. Nut ellipsoid, plano-convex, dark brown.
