Similar to S. sumatrensis and S. multifoliata, but generally easily distinguished 

 by the globose white nut. Panicle usually slenderer than in S. sumatrensis, secon- 

 dary bracts less conspicuous. Glume to the nut broadly ovate at base, shortly acute. 

 Nut -rg-J in. in diam., depressed -globose, somewhat trigonous; lobes of disc-margin 

 somewhat thick, white with green nerves, at tip entire or slightly crenate-toothed. 



Sect. 3. SCHIZOLEPIS (Genus), Nees in Mart. FL Bras. ii. (pars. 1) 158, 

 186 (char, extended). Character of Elatte, but rim of disc-margin with 

 numerous triangular or lanceolate teeth. 



29. S. bracteata, Cav. Ic. v. 34, t. 457; robust, hairy, partial 

 panicles several upper male with numerous small spikelets, lower fern, with 

 fewer larger spikelets (1-sexual plants also occur), style 3-fid, nut 

 globose verrucose, rim of disc truncate rigid crenulate or scarcely toothed.

 H.f. Sf T. Assam, Masters (in Herb Kew). This Assam plant cannot be separated 

 from Schizolepis. It is not easy to conjecture how it could be introduced into Assam ; 

 but I believe it to be only a form of the purely American S. bracteata nevertheless.

27. KOBRESXA, Willd. 



Glabrous, nearly smooth, perennials. Stem simple, bearing grass-like 

 leaves near base only and one cylindric or oblong terminal spike, or (in 

 sect. 4) leaves and several loosely panicled spikes. Spikes (apparently often 

 simple) 1-sexual, or 2-sexual (when fern, spikelets inferior). Spikelets male, 

 or fern. ]-fld., or bisexual with one fern, fl, at base. Fern, glumes (the 

 bracteole to spikelet) homologous with utricle of Carex, its margins in 

 their lower half more or less connate in their upper half free, forming 

 thus frequently an imperfect utricle (which in bisexual spikelets encloses 

 rhachilla of male 1-4-fld. upper portion of spikelet). Style 3-fid (in J. 

 wiacrantlia 2-fid). Nut usually as long as glume, oblong or narrowly 

 obovoid, trigonous (in K. macrantha flat). Species 20, N. temp, region. 



Sect I. HEMICAREX (Gen.) Benth. in Gen. PL iii. 1072 (chiefly). Stem 

 with 1 apparently simple linear or oblong spike. Fern, spikelets 1-fld., 

 with sometimes the rudiment of rhachilla within fern, glume. Style 

 3-fid.
