18. S. Sadula, Hance in Ann. Sc. Nat. ser. 4, xviii. 232; robust, 

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

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

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

 Fl. Hongk. 400 (not S. levis, Retz). S. aspera, Boeck. in Linnssa, xxxviii.

MALAY PENINSULA. PERAE, alt. 300 ft., King's Collector (n. 1929). DISTRTB. 

 Hongkong. 



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

 scabrous, by the rhachis and rhacheolse being scabrous (scarcely hairy), and by the 

 nut being smooth (scarcely tessellate). 



19. S. psilorrhiza, G. B. Ctarke ; 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 subrenexed. 



Herb. Kew "a CALCUTTA communicata j" specimen in fine fruit. There is 

 what I take to be a young 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 5 in. ; sheath 3-winged ; ligule ovate, obtuse 

 glabrous. Panicle 2-2J by $ in., stout, rhachis somewhat hairy; lower branches 

 0-^ in., secondary bracts ^-1 in. filiform. Sptkelets all unisexual, as of S. hebecarpa 

 and S. elata ; fern, glume aristate. Nut -g- in. long, ovoid, scarcely at all trigonous 

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

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

 Stocksiana. 



20. S. oryzoides, Presl Rel.Haenk. 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.

Sto Ions long, terete, i in. in diam., usually without scales (because in water). 

 Stems 36 ft., scabrous. Leaves up to 3 ft. by | 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. Fern, spikelets in. ; 

 fern, glume scarcely mucronate. Nut 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 obscurely, 

 iged. 



f Leaves (that is those next below the bracts) almost regularly alternate. 



21. S. Hookeriana, Boeck. in Linnasa, xxxviii. 498 ; robust, more 

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

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

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