The above generic characters (drawn up in accordance with Ur. 

 Trimen's rules for this Flora) would exclude many species of the genus. 



Mid lobe of lip obcordate I. C. PURPUREA. 



Mid lobe of lip bipartite 2. C. veratrifoll\. 



1. C. purpurea, Lindl. Gen. and Sp. Orch. 249 (1833).

 Thw. Enum. 308 (non Lindl.). Trim. Syst. Cat. Ceyl. 88. C. P. 2366.

Rootstock stout, with vermiform roots, bearing a row of 

 close-set annulate pseudobulbs \-\ in. long; stem erect; 1. 

 many, 12-18 in., ovate-lanceolate, acuminate, tapering into 

 the broadly sheathing ribbed petiole, pubescent on both sur- 

 faces, 7-costate beneath; ped. 8-10 in., stout, and raceme 

 6-8 in., tomentose, few or many-fld., sheaths lanceolate, herba- 

 ceous ; bracts \-\ in., ovate-lanceolatc, longer or shorter than 

 the long pedicels, persistent ; fl. i-ii in, broad ; pedicel with 

 ov. I- 1 "2 in.; sep. ovate-oblong, apiculate, 5-veined, pubescent; 

 pet. shorter, broader; lip shorter or rather longer than the 

 Sep., side lobes oblong, obtu.se, falcate, mid lobe cuneately 

 obcordate, or 2-cleft, disk prominently warted at the base, 

 spur slender, i in. or more, obtuse, pubescent ; pollinia narrow,

 pedicel.

Very near C. A'lasiica^ Lindl.. of India and Java, well figured in Bot. 

 Reg. 1844, t. 37 and Bot. Mag. t. 4541, which differs in its leaves glabrous 

 above, and in the larger flowers with a different lip. This was also 

 recorded from Ceylon by Lindley (Macrae), and may possibly occur, 

 being widely distributed in India.
