THE CYPEliACE.^: OF THE BOM RAY PRESIDENCY. 691 



li. Spikelets in a contracted umbel, pinkish 



grey, roots wooly . . . . . . 2'}. C. c<mf/loitu'ratui>. 



4. Spikelota in a contracte«l umbel, roots wiry. 26. C. athinsoni. 



K>- C. teneriffae, I'oir. l-l inches lugh. I'arcly more, tuiVed. 

 Spikelets usually few, largt^ for the size of the plant, bearing a 

 superficial resemblance to the spikelets of C. compressus. 



Barren waste land, occasional in the Deccan and Carnatic. (Indo- 

 African). 



17. C> uncinatUS, l^oir. (in Cooke's F.B.P.). C. casiyidatus, 

 H. B. and K., in F.B.I. 3-G inches high. Tufted. Spikelets 

 small and narrow. Nut minute, obovoid. 



Very rare. Specimens from Igatpuri in Herb. St. Xavier College are 

 not certainly allocable to this species or the next for want of mature nuts. 

 (African and E. Asian). 



18. C- castaneus, WUkl. 1-7 inches high. Tufted. Spike- 

 lets very small and narrow, dark chestnut. Nut minute, exact!} 

 oblong. 



Very rare, Koukan. (Scattered throughout S. E. Asia.) 



Note. — Here belongs C. pulckerrimus, Willd., given by Cooke on the 

 strength of the record " Sind, Pinwill" in F. B. I. It is very close to the 

 next, but has more numerous umbel rays and crisped incurved tips to the 

 glumes. It should not occur in Sind, being a plant of the inner Indo- 

 Malayan region. 



19. C. difformls, Linn. Very variable in size, from 4 inches 

 to 2 feet. Stems tiaccid triquetrous, bracts long, leafy. Inflores- 

 cence of one head or of several umbelled globose heads of innumer- 

 able, densely-crowded, short, very narrow^ spikelets, green when 

 3'oung, almost always dark-brown or blackish when ripe. Glumes 

 short, very obtuse. 



Abundant throughout the whole Presidency in damp places, or in stand- 

 ing or running water. (Warm regions of the old world). 



20. C. flavidus, Retz. 1 inch to 1 foot. Tufted but, not 

 densely so. Stem flaccid. Umbels compound or decompound 

 with long rays, occupying most of the plant. Bracts long. Spike- 

 lets ^ inch, very narrow, very acute, golden yellow, stellately 

 spreading from the tips of the rays. Glumes oblong with rounded 

 hyaline tips and hyaline sides. Nut minute (as clavis) white. 



A very abundant weed of rice- fields throughout the Presidency. (Warm 

 regions of the old world), 



21. C. Haspan, Linn. Closely resembles the last, but 

 larger in all its i)arts and with a creeping slender rhizome. Nut 

 as clavis, but probably would have obtuse faces in a perfectly 

 mature state, white in the Bombay examples.
