686 CLXXII. CYPERACEJE. (C. B. Clarke.) [Selena. 



Spikelets much clustered, many bisexual in. long, nearly smooth and glabrous, 

 very similar to those of 8. pergracilis but larger. Nut T \j in. long (sometimes much 

 smaller) ellipsoid, trigonous, base narrow trigonous. 



Var. /3 (Roxburghii), Thw. Enum. 354 ; rather stouter, nut rather larger with 

 pyramidal subacute apex, transversely wrinkled by ferruginous glands (at least when 

 young). Hypoporum Eoxburghii, Nees ms. Ceylon, Thwaites ; Deccan Peninsula, 

 Wight. Partial panicles much more rigid, subpyraniidal, clusters of spikelets more 

 numerous and dense. This might be esteemed a species, but too much regard must 

 not be paid to the reticulation or wrinkling of the nut in Scleria, which arises from 

 irregularities in drying, &c. The outer cells of the nut in Scleria are in every species 

 small, quadrate-hexagonal, obscure. 



3. S. corymbosa, Eoxb. Fl. Ind. iii. 574; robust, coarse, nearly 

 glabrous, panicle long copious of several compoundedly-corymbose axillary 

 partial panicles, style 3-fid, nut white, smooth, disc very ^mall. S. andro- 

 gjna, Nees in Linnsea, ix. 303, & Wight Contrib. 117 ; Thw. Enum. 353 ; 

 Boeck. in Linnsea, xxxviii. 536. S. majus, Moon Cat. Pl.^Ceyl. 62. S.

Warm moist region, sparsely scattered from KHASIA TERAI, J.D.H., to CEYLON, 

 Thivaites, and MALACCA, Griffith. 



Rhizome horizontal, often ^ in. in diam., clothed with brown scales. Stems 

 3-8 ft., stout ; sheaths triquetrous, not winged. Leaves 20 by 1 in. j margins sca- 

 brous. Infl. 1-2 ft. by 4-6 in. ; lower peduncles exserted 1-4 in., rigid. Spikelets 

 i in. long, nearly all bisexual, clustered and solitary, usually brown or straw-coir d., 

 sometimes more or less chestnut-colrd., constructed nearly as in 8. lithosperma 

 but stouter j stamens often 3. Nut nearly in. long, ellipsoid, subtrigonous, much 

 narrowed at base. Disc slightly dilated, scarcely 3-lobed, yellow-brown ; margin 

 (inner disc of authors) very short, subtriangular, glandular, often dark red. 



4. S. Hidleyi, (7. B. Clarke; slender, nearly glabrous, panicle of 

 few small very distant axillary corymbs, style 3-fid, nut white smooth 

 apiculate, disc very small. 



SINGAPORE ; Pular Buru, Ridley (n. 1641). DISTEIB. Hongkong. 



Rhizome horizontal, in. in diam., clothed by small ovate striate dark -red scales. 

 Stem 2 ft., -Jj, in. in diam., triquetrous, scabrous ; sheaths very narrowly winged ; 

 ligule almost truncate, margin narrow scarious hardly hairy. Leaves 12 by ^ in. 

 Partial panicles scarcely 1 in. in diam., lowest 4-8 in. from the next, with about 

 8-20 spikelets. Nut-bearing spikelets usually with male fl. at top, other male spike- 

 lets also added. Nut (rather more pointed) and disc as in S. corymbosa, Roxb., to 

 which Boeckeler has referred it and which is the true affinity ; but the difference in 

 stoutness, stem-leaves, and panicle is very great. 



Subgenus II. SCLERIA proper. Bisexual spikelets none or few. 



Sect. I. TESSELLAT^E. Slender (sometimes tall) plants. Eoots fibrous, 

 or the rhizome very short not thick. Leaves not caudate-setaceous at tip. 

 Panicle narrow, the lower axillary panicles often remote, reduced to spikes, 

 sometimes very short. 



* Nut tessellated. 



5. S. tessellata, Willd. Sp. PI. iv. 315 (excl. cit. Humph.) ; slender 

 sometimes tall, hairy or glabrate, roots fibrous, panicle elongate thin 

 lower branches remote, style 3-fid, nut tessellate, lobes of disc-margin 

 short ovate erect thin pale. Nees in Wight Contrib. 118; Thw. Enum.
