Similar to S. sumatrensis and S. vmltifoliata, but generally easily distingnished 

 by the globose white nui.—Fanicle usnally slenderer than in 8. .sumatrensis, secon- 

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

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

 from Schixolepis. 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. braoteata nevertheless.

Qlalrous, 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 fem. spikelets inferior). Spikelets male, 

 or fem. 1 -fid., or bisexual with one fem. fl. at base. Fem. glumes fthe 

 bracteole to spikelet) homologous with utricle of Garex, 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 

 rhaohilla of male 1-4-fid. upper portion of spikelet). Style 3-fid (in K. 

 rnacrontha 2-fid). JVut usually as long as glume, oblong or narrowly 

 obovoid, trigonous (in X. macrantha flat). — Species 20, IT. temp, region.

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

 with sometimes the rudiment of rhachilla within fem. glume. Stvle 

 3-fid.
