C. insigne, var. Exul; Ridley in Gard. Chron. (1891) vol. ii. p. 94. 
C. Exul so closely resembles C. insigne, Wall., of the 
Khasia Hills (tab. 8412) that it may, I think, well be 
doubted whether Mr. Ridley was not right in referring it 
as a variety to that plant. The chief structural difference 
between them that I can detect, is in the form of the 
staminode and stigma ; the staminode in C. insigne being 
more obovate, narrowed and entire posticously, and its 
stigma is very much smaller. ‘The pubescence is the same 
in both, as is the great glabrous bract, and the scheme of 
colouring of the perianth, though differing in detail. On 
the other hand, (. Hzul is much the larger and handsomer 
plant of the two. 
Tonka, in the Siam Peninsula, is the native country of 
C. Evul, whence plants were sent to the Botanical Gardens 
of Singapore and described by Mr. Ridley, as cited above. 
The fine specimen of it here figured was obtained for the 
Royal Gardens, Kew, from Messrs. F. Sander & Co., St. 
- in 1892. It flowered in a warm Orchid House in 
arch.
