672 CLXXII. CYPERACE.E. (C. B. Clarke.) [Rynchospora 



sessile, turgid, chestnut-brown, with 12 -18 transverse wrinkles, beak (in the Old 

 World examples) broadly conic, smooth or nearly so. [The names glauca and 

 gracilis were published in the same volume. Many authors prefer the gracilis 

 supposing the species to be Swartz's Schcenus gracilis. But Swarf z says his Schcenus 

 gracilis had a 3-fid style, so that it was no Rynchospora (except perhaps in small 

 part by mixture) ; Mr. Bentham has hence adopted glauca.] 



Var. /3 cliinensis (sp.) Boeck. I.e. 586 (not of Nees & Meyen) ; spikelets longer 

 up to i in. often bearing 2 nuts, beak longer often equalling f nut, hypogynous 

 bristles usually reaching top of beak. R. glauca, BoecJc. I. c. 585 (partly). R.

 Borneo, China, Sandwich Isles. A maritime form. 



10. R. Griffith!!, EoecTc. in Linnsea, xxxviii. 404, nut narrowly 

 obovoid ellipsoid rounded at top, beak f nut, hypogynous bristles reaching 

 top of beak scabrous ; otherwise as R. glauca.

Var. /3 LEVISETIS ; hypogynous bristles 6 twice nut smooth. R. chinensis, 

 "forma tenuis," Boeck. 1. c. 587. Upper Sikkim ; Lachen and Lachoong, alt. 

 10,000 ft., in wet meadows. J. D. H. A remarkable form, an alpine state of 

 -5. Griffithii. The nut is narrow, so that Boeckeler's alliance of it with the sea- 

 coast R. chinensis is not satisfactory. 



11. R. sikkimensis, G. B. Clarke] glabrous, panicle narrow, 

 corymbs rather small, spikelets numerous bearing 3-6 nuts, hypogynous 

 bristles 6 scabrous twice nut, style- branches 2 long, nut small narrowly 

 obovoid truncate, beak ovoid longer and broader than nut smooth (otherwise 

 as R. Griffithii). 



UPPER SIKKIM ; Catsuperri Lake, alt. 8000 ft. J. D. H. 



Spikelets in., fine brown, with 12-18 glumes and 3-8 pistilliferous flowers. 

 This plant may be the R. chinensis described by Boeck. in Linnsea, xxxvii. 587, 

 which he says has about 5 fertile flowers to the spikelet ; but it does not agree in 

 this particular with Thtvaites n. 677, which is Boeckeler's type of R. Chinensis. 



UNDETEEMINAL SPECIES OP EYNCHOSPORA. 



Scirpus (Rynchospora ?) MOLLIS, Wall, in Roxb. Fl. Ind. [ed. Carey and Wall.'] 



i. 227 ; stems 1-2 ft. hairy, leaves few towards base of stem hairy, umbel 7 -rayed, 



. spikelets oblong, glumes ovate subaristate smooth, hypogynous bristles 3 long hairy, 



style compressed hairy and ciliate with broad cordate articulate base. Fimbristylis ? 



mollis, Kunth Enum. ii. 246. 



NEPAL; Wallich. 



The style being compressed must be assumed to be 2-fid ; this, joined to the 3 

 long hypogynous bristles, would fix the plant in Rynchospora (as suggested by 

 Wallich), but it cannot be referred to any known Indian species of that genus. 



15. SCHCENUS, Linn, (in part}. 



Spikelets capitate or panicled ; flowers axillary. Glumes (except the 

 uppermost tabescent) distichous ; 3 (or more) lowest empty, 1-4 following 

 perfect, nut-bearing, somewhat remote. Hypogynous bristles often present, 

 setaceous, not dilated at base. Stamens 3, anterior. Style 3-fid, gradually 

 passing into the nut without any constriction below style-base. Nut in a
