604 CLxxii. cypEEACE^. (0. B. Clarke.) [Oyperus. 



Throughout India, excepb the dry west, commou from Sikkim and Assam to 

 Ceylon and Penang. — Disteib. All warm regions. 



Glabrous. SMzome very short ; roots wiry. Stems 8-30 in. Leaves often as 

 long as stem, i-| in. broad, flat, green, S-nerved. Umlel 4-12 in. in diam., decom- 

 pound (depauperated examples with few spikes occur) ; bracts 4-10, up to 1-2 ft., 

 leaf -like. Spikelets 3-9 together, digitate, J-^ by ^-^ in. (sometimes much longer). 

 O-lumes boat-shaped, green, back 3-5-nerved ; wings of rhachilla narrow, not deci- 

 duous. Stamens 3-2 ; anthers small, linear-oblong, often (when young) with a small 

 linear-lanceolate crest. Nut dusky black ; style much shorter than nut, sometimes 

 hardly any ; branches linear, shortly exsert. — One of the commonest of the genus, 

 best known as 0. elegans, Linn., but no part of Linneeus's elegans, whose type, his 

 figure cited, and his description, are all of Q. viscosus, Aiton. Nor can his descrip- 

 tion include 0. diffustis, Tahl. Kunth, in transferring the name 0. elegwns, Linn., 

 to this plant, followed Swartz and Willdenow. 



21. C. pubisquama, Stewd. in Zoll. Verz. Ind. Archip. ii. 62 and Syn. 

 Gyp. 20 ; spikelets very numerous rigid, glumes minutely muoronate often 

 puberulous, their upper margins tightly imbricate even in fruit (otherwise 

 as G. diffustis). Miq. Fl. Ind. Bat. iii. 266. 0. lagorensis, Stead. Syn.

From Assam and Buema to Pebak and Ceylon. — Disteib. Malay Islds. 

 Diflfers, uniformly, from large examples of 0. diffksus, Vahl in the tightly- 

 packed glumes (even in fruit) ; but might be treated as a var. 



22. C. Kelferi; Boeck. in lAnnsea, xxxviii. 360; middle-sized, umbel 

 middle-sized flaccid, glumes distant ovate-lanceolate shortly mucronate, 

 nut f length of glume (otherwise as G. diffusus). C. B. Clarke in Journ. 

 Lirni. Sac. xxi. 128.— FimbristyUs, Wall. Oat. 3628.

23. C. multispicatus, BoecJc. in Linnsea, xxxviii. 362; umbel very 

 decompound, spikelets many solitary compressed slenderer, glumes densely 

 imbricated minutely mucronate, nut ^ length of glume (otherwise as G. 

 diffusus). G. B. Clarke in Journ. Linn. Soc. xxi. 129 (and 14, 0. multi- 

 striatus, by error). 



Cachae; Keenan. Tbnassbeim or Andamans ; Heifer {Kew Disti-ih.ei6Z). 



Umbel 12-16 in. across; spikelets innumerable, in Heifer's specimen nearly all 

 pedicelled solitary, in Keenan's about half solitary haH 2-3 together digitate. 

 Glumes in fruit with upper margins imbricated. 



24. C. Kurzii, G. B. Clarke in Journ. Linn. 8oc. xxi. 129 ; umbel 

 very decompound secondary rays rigidly divaricate, spikelets 20-40-fld. 

 wings of rhachilla broad persistent, glumes closely imbricate tip triangular 

 acute scarcely mucrdnate (otherwise as C. multispicatus).

This does not match any of the foregoing closely-allied species (nn. 20-24 

 inclusive). 



25. C. turffidulus, G. B. Gla/i-ke in Journ. Linn. Soc. i. 130 ; stem at 

 top triquetrous almost 3-winged, umbel dense secondary rays divaricate, 

 spikelets few-fld. turgid sometimes almost terete clustered in small globose
