ME. C. B. CLAEKE ON INDTAN SPECIES OF CYPEKFS. 201 



The spicula becomes more slender, or finally acicular, and we 

 arrive at forms named by some cyperologists C. cylindrostachys, 

 by others C. cyperinus. 



Among the great diversity of forms I do not find one that seems 

 to me to be conspecific with C. ovularis, Torrey ; and that is 

 Mr. Bentham's opinion. 



Var. (3. panicea; spicis parvis subsessilibus ; spiculis parvis, 

 anguste oblique lanceolatis, gluma mascula hermaphroditam 

 parum superans. 



C. paniceus, BoecJc. in Linncea, xxxvi. p. 361. 



Kyllinga panicea, Rollb. Descr. et Ic. p. 15, t. 4. fig. 1, non Mariscus 

 paniceus, Kunth. 



Zeylania (Thwaites n. 2878, h. Calcutta). 



Madras Peninsula (Heyne in Wallich nn. 3435, 3436, h. Cal- 

 cutta) ; Palaverum Hill ( Wiyht in Wallich n. 3435, h. Cal- 

 cutta). 



Var. y. picta, Wallich MS. ; spicis fere sessilibus subglobosis, 

 albidis aut glauco-purpurascentibus ; spiculis late oblongis, gluma 

 mascula quam hermaphrodita vix lougiore. 



Mariscus Wallichianus ? Kunth, Enum. ii. p. 11/. 



Tranquebar (Bottler n. 648, h. Calcutta). 



Ins. Nicobar (Kurz, h. Calcutta). 



Yar. S. laxata; rhizomate elongato, ramoso, tenui; culmis 

 elongatis, tenuibus, flaccidis ; spicis breviter pedunculatis, laxis, 

 ovoideis, 1-5-spiculosis ; spiculis anguste lanceolatis, gluma her- 

 maphrodita quam spicula multo breviore. 



Zeylania {Thwaites C. P. n. 817, h. Calcutta). 



Madras Peninsula (Heyne, h. Calcutta). 



Var. e. cylindrostachys ; spicis elongatis cylindraceis, 8#pe 

 longius pedunculatis, undique patentim vel subdeflexim dense 

 spiculigeris ; spiculis anguste lineari-lanceolatis ; gluma herma- 

 phrodita tertia quam superiores vix breviore aut multo breviore. 



Bengalia orient alis (Griffith n. 6242, h. Keio). 



Nepaul ( Wallich n. 3437 a, h. Calcutta). 



Tenasserim v. Andamans (Heifer n. 6243 / 1, h. Calcutta). 



Borneo (Barber, h. Calcutta). 



This variety is defined only by the inflorescence : the structure 

 of the spikelets varies from that in C. umbellatus type very nearly 

 to that in C. biglumis: the spikelets vary in length from 2 to 

 millim. Those examples in which the 4th (and 5th) glumes much 

 overtop the 3rd are named C. cyperinus &c.
