138. CYPERACE.E. [1. Cyperus. 



the nut as obovate-oblong, fuscous, etc., in fact almost exactly as in 

 nutans. The type {Wall. No. 334(36) is a robust plant Avith several 

 stems from a short rhizome, clothed with leaf- bases. Primary rays 

 of umbel 2-4", each bearing a very close umbel of grey spikes •6--8" 

 long. 



Ranchi, Clarke ! Hazaribagh, Clarke ! Moiigbyr, Wall. ! 



18. C. Thomsoni, Boeck. 



This is another plant of the disfa7ig o-roup which has been found in the Sikkim 

 Tarai close to Puriieah, and hence is probablj^ in onr area. 



Rhizome short woody and with general habit of nutans. Inflorescence grey 

 shining rather feathery from the close large spikelets having elongated internode's 

 to the rhachilla. The glumes are thus loosely imbricate as in dhtans, but -18" 

 long, with 7-9 very close dorsal nerves. Nuts oblong or ellipsoid, only a little 

 over half as long as glume or less, black, top acutely pjTamidal. 



19. C. malaccensis, Lam. 



Habit rather various. Rhizome creeping woody and with long 

 stolons under -2" diam. clothed with broad lax dark chestnut scales 

 1" long. Stems robust, up to 3 ft. sharply 3-quetrous. Umbels large 

 spreading 7-8" across lax, or rather dense and only 2-3", simple 

 compound or congested with very long involucral bracts. Spikelets 

 almost terete, glumes up to 14, oblong when unfolded with rounded 

 back and margins incurved all round when dry, -07—09" long. Nut 

 very narrowly oblong, fths length of glume, 3-gonous, ultimately 

 black. 



Brackish mud bauks, Clarke. Sandy tracts, Walsh. Puri, Walsh ! 



Stems with concave faces above. L. usually few, erect, ensiform. clothing base 

 of stem with their sheaths, uppermost 2-6" long. Spikes of -i-lO spikelets -Z-'l" 

 long linear. Glumes about 11-nerved, with narrow rather coriaceous margins, 

 not keeled, apex rounded; only Jj" long according to F.B.I., but some specimens 

 named by Clarke have them nearly "l", so that this is probablj- a mistake. 



P>-aj« says " stem terete," but irt/««reA- distinctly states that his malaccensis i?> 

 3-quetrous and it is often 3- winged at the top. Walsh's specimen (named by 

 Clarke) is not very characteristic, moreover, the rhachilla is distinctly winged. It 

 is, I thiuk, tegetifurmis, though malaccensis very likely occurs in C attack and Puri. 



20. C. tegetiformis, Roxb. 



A robust sedge I -5-5 ft. high with 3-gonous stems or 3-ciuetrous at 

 the top not or obscurely septate and long stolons. Leaves hardly 

 any. Bracts short, rarely half the length of the umbel, the rays of 

 Avhich attain 3-5". Spikelets in short spikes or corymbs, 4-16 together, 

 linear, compressed, -5-1" long, glumes closely imbricate, -1" long, 

 back with 6-7 -nerved keel or rounded and striate with brown ami 

 faintly 5-9-nerved ovate-oblong (when unfolded). Rhachilla Avith 

 linear hyaline wings embracing the ovary. Anthers linear, minutely 

 apiculate or muticous {Cooke). Style •03—04", Nut -05" oblong, 

 3-gonous, black. Style -03—04" with stigmas -05—08". 



Gaya, Nuskerl Puri? (see remarks under malaccensis). Fl. Oct. 



There is only one specimen from our area (Gaya) which has been named in the 

 Cal. Herb, and that appears to me doubtful and is possibl.y C. cort/mbosus. The 

 bracts shghtly exceed the um])el and the erect spikelets are Very young. Glumes 

 •11" long, back -with 5 slender nerves, anthers 3 minutely apiculate, wings of 

 rhachilla very obscure, nut undeveloped. Most of the specimens named by 

 Clarke are from Lower Bengal and Eastern Bengal. I suspect that the length of 

 the involucral bracts is not a good character, especially in inflorescences of 

 diiferent stages of growth.
