138. CYPERAGE.E. [2. Pycreus. 



about -I-'IT" broad, rhachilla not as deeply excavated as in stramineus. 

 Glumes rather loosely imbricate -06" or usually •OS--!" long, ovate 

 cymbiform, obtuse, nerved on the back. Nut white or brown, -04" 

 long smooth, hardly half length of glume, outer cells all subquadrate 

 hexagonal. 



Udeypur, Prain's Collector ! Sautal Parg-., Kui-z ! Fl. Au,£y.-Feb. 



Stem decumbent at the base, often clotlied one-third its length with leaf-sheaths, 

 the leaves thus some distance from the base of the stem. Bracts 3-5 foliaceous, up 

 to 5" Ions'. Spikelets 6-24.-fld. Nut in the Udeypur specimen is almost orbicular 

 but not symmetrical, much compressed. The stems are clothed with short lateral 

 branches each terminating in a head. 



4. P. pumilus, nov. comb, (not of F.B.I.). Syn. P. nitens, Nees; 



Cyperus pumilus, L. 

 Short and tufted 1-6" or laxer and 10" high. Spikelets pale or 

 somewhat silvery small, clustered or shortly spicate, the head (or 

 spike) solitary or in a simple umbel with a central sessile cluster and 

 2-6 i-ays 2-3" long or less. Glumes very small, •04--05" long, or 

 -06" with the cusp, boat-shaped or narrowly oblong mucronate or 

 cuspidate from the excurrent keel. Stamen usually 1 only. Nut 

 somewhat obovoid, brown or grey, -02" long. 



Moiighyr, Hum., Clarke \ Santal Parg., common, Kurz, Gamble \ Ranchi, 

 Clarke, common, etc. ! Hazaribagh, Clarke ! Probably throughout the province. 

 Fl. Sept. -Nov., May. Annual. 



L. shorter or as long as the stem, "O-o-'l" broad, weak, l-nerved, acute. Heads 

 of spkts. •25-1" diam. Bracts 3-4 foliaceous up to 4" long, Spkts, •17-'6" 

 long, 20-50-fld., rhachilla slender, persistent. Glumes sometimes 2-fid or -lobed 

 with rounded lobes and with green keel, 3-5-nerved and with rounded hyaline 

 nerveless sides. Stigmas about as long as style. Nut (under high magn.) with 

 longitudinal lines of small isodiametric cells raised in the centre. 



It appears to be very closely allied to Cyperus Jlavidus, Retz. 



5. P. globosus, noi'. cow6. Syn. P. capillaris, x\^ees ; Cvperus globosus, 

 - All. 



A very slender annual with tufted stems up to 16" high and very 

 slender almost filiform erect leaves and bracts. Inflorescence often 

 compound Avith several short raj-s and a central sessile subglobose 

 spike bearing pale brown to deep brown linear much-compressed 

 spkts. at right angles to the rhachis. Umbels sometimes reduced to 

 a single head. Gl. -OS-'OO". Nut ellipsoid apiculate chestnut-brown 

 to black -03". 



Ranchi, Wood ! Hazaribagh, Clarke ! Also in the Upper Gangetic Plain and 

 extending eastwards so that it probably occurs in all our Northern Tract. Fl. 

 Oct.-Jan., also May (in Tarai). Annual. 



Stems 3-gonous. L. 4-12" weak. Rays of umbel usually very short but 

 attaining 2-5". Bracts 4-8". Spkts. variable in length, "d-'b" by '1" or in some 

 Khasia specimens 1*3" long by 'IS". Glumes ovate-oblong or ovate-obtuse, closely 

 imbricate. Rhachilla stout 4-gonous. Stamens 2. Stigmas as long as style. 



Var. stricta, Clarke. Spkts. narrower straw-coloured or yellow less compressed 

 frequently short only 6-12-fld., sometimes curved or twisted, gl. closely packed but 

 loosely imbricated. Chota Nagpur, Clarke. 



6. P. odoratus, Beauv. Syn. P. polystachyus, Beauv. ; Cyperus 



odoratus, L. 

 A very small tufted sedge only 2" high but often attaining 15" Avith 

 very close capitate spikes of radiating spikelets, the umbel simple
