KASHMIEJ alt. 1000 ft., Jacquemont, ,&c. PUNJAB; alt. 1000 ft., Thomson, 

 &c. DISTEIB. from Spain to Japan. 



Glabrous, except sometimes rhachis of spikes. Stems solitary, 1-3 ft. Leaves 

 often as long as stem, 5 in. broad. Bracts 3-5, up to 8-18 in. leaf-like. Umbel 

 rays 3-6, up to 2-6 in. long, very unequal, ratber stout ; nmbellules shortly corym- 

 bose or capitate ; bracteoles sbort. Spikes of 5-40 spikelets. Spikelets ^- by T V-i 

 in., 12-30-fld. (or sborter 6-8-fld.), turgid ; rhacbeola robust, tetragonous, excavated, 

 scarcely winged. Glumes approximate ; margins narrowly scarious, in dried ripe 

 examples incurved crisped. Stamens 3 ; anthers scarcely apiculate. Style 'short ; 

 branches about as long as nut. Nut obovoid, obtuse, smooth, dark -brown. Much 

 confused in herbaria with Cyperus pilosus, Vahl, which it generally resembles and 

 has further the rhachis of the spikes minutely hairy, a rare character in Cyperus. 



2. J. stylosus, C. B. Clarice ; stem at top trigonous slender, leaves 

 and bracts rather short, glumes not striate towards their margins, style- 

 branches very long, nut (not quite ripe) small; otherwise as J. serotinus.

KHASIA HILLS ; Griffith. 



Leaves not half length of stem. Bracts scarcely overtopping inflorescence. 

 Rhachis of spikes glabrous. Glumes chestnut-red, with very narrow white margins, 

 inflated as in J. serotinus. Spikelets comose from the persistent long dark-red styles. 

 Nuts perhaps all imperfect. 



3. J. inundatus, C. B. Clarke ; stout, stem at top triquetrous thick, 

 leaves and bracts long, umbel compound, spikelets in loose spikes, glumes 

 obtuse 5-7-nerved, nut longer than | the glume. Cyperus inundatus,

BENGAL; in swamps, from Sylhet to the sea, frequent. DISTEIB. China. 



Rhachis of spike glabrous, 1-2 in., spikelets often | i in. apart. Differs little 

 from J. serotinus, but by the open spikes. In herbaria it is more frequently mixed 

 either with Cyperus procerus or Pycreus puncticulatus. 



4. J. alopecuroides, C. B. Clarke; large, leaves and bracts long, 

 umbel large compound, spikes cylindric very dense, spikelets linear-oblong 

 bearing 8-30 nuts, glumes concave dirty straw-colour, rhachilla rather stout 

 subquadrangular not winged, nut small -| length of glume. Cyperus

A large glabrous annual, 2-3 ft. Leaves often as long as stem, - in.

 bearing at apex 2-4 ebracteolate spikes. Spikes 1-1 by f in. Spikelets % in., 

 lanceolate, compressed. Glumes muticous or mucronulate. Stamens 3 ; anthers
