18. S. B,adula« Hance in Ann. 8c. Nat. ser. 4, xviii. 232 ; robust, 

 scabrous, very slightly hairy, partial panicles several pedanoled pyramidal, 

 secondary bracts long setaceous conspicuous, style 3-fid, nut smooth 

 white, lobes of disc-margin small ovate. S. laevis, var. soaberrima, Benth.

Closely allied to robust forms of S. elata, Tliwaites, but differs by being very 

 Bcabroua, by the rhachis and rhacheoliB being scabrous (scarcely hairy), and by the 

 nut being smooth (scarcely tessellate). 



19. S. psllorrhiza, O. B. Clarke ; robust, nearly glabrous, rhizome 

 wiry slender, panicle contracted nearly to a linear-oblong dense spike, 

 style 3-fid, nut large smooth white, lobes of disc-margin 3 very short obtuse 

 thick sabreflexed. 



Herb. Kew " a Calcutta communicata ;" specimen in fine fruit. — There ia 

 what I take to be a jouiig example of the same species from Cambodia. 



Rhizome creeping, ^ in. in diam., clothed by distant ovate striate red scales. 

 Stems 2 ft., scabrous. Leaves 1 ft. by i in. j sheath 3-winged ; ligule ovate, obtuse 

 , iglabrous. Panicle 2-2i by | in., stout, rhaohis somewhat hairy; lower branches 

 0-^ in., secondary bracts ^-1 in. filiform. Spikelets all unisexuiil, as of S. heheearpa 

 and S. elata ; fem. glume aristate. Nut ^ in. long, ovoid, scarcely at all trigonous 

 or hairy; disc obpyramidal, rigid, pnrpurescent, margin very narrow with rigid 

 yellowish lobes. — Quite unlike the five last sp., and is perhaps more allied to iS. 

 Stocksiana. 



20. S- oryzoidesj Presl Bel. Hobenk. i. 201 ; robust, glabrous, panicle 

 one terminal nearly bractless dense with numerous long suberect branches, 

 spikelets solitary spicate, style 3-fid, nut smooth white, disc truncate.

Stolons long, terete, i in. in diam., usually without scales (because iu water). 

 Stems 3-6 ft., scabrous. Leaves up to 3 ft. by f in., margins very scabrous, tip 

 suddenly narrowed ; sheath 3-winged or not rarely nearly wingless ; ligule 0. 

 Panicle long-peduncled, 6 by 3-4 in. ; branches often once divided, secondary 2 in., 

 simple. Spikelets unisexual ; some plants are nearly male ; in others the fern, spike- 

 lets (much less fewer than the males) are near base of spikes. Fem. spikelets J in. ; 

 fem. glume scarcely mucronatc. Nut i. in. in diam., globose ; lobes of disc extremely 

 short reflexed (Nees by some error says the perigynium is profoundly 3-lobed 

 adpressed to the nut). 



** Sheaths (of middle stem-leaves) triquetrous, not, or very ohscurely, 

 winged. 



t Leaves (that is those next helow the bracts) almost regularly alternate. 



21. S. Kookeriana, Boeck. in Linnsea, xxxviii. 498 ; robust, more 

 or less hairy, partial panicles 1-3 lanceolate or ovoid branches erect, 

 spikelets chestnut-colrd., style 3-fld, nut very obscurely reticulated, lobes 

 of disc-margin (obscurely 3) broad obtuse thick reflexed.— Scleria ap., n. 13,
