Descr. The pseudo-bulbs I have not seen: they are 
probably not different from the other species of the Genus. 
‘The leaves are unusually large, four inches and more broad, 
thin and membranous, many-nerved, acuminated at the 
point. Scape much thicker than a swan’s quill, jointed, 
with a scale at each joint. Flowers large, secund, diffusing 
a peculiar and heavy smell. Perianth forming an arch over 
the column and pointing forward. Sepals and petals nearly 
equal, ovato-lanceolate, acuminate, concave, green tinged 
with purple; the petals blotched with red purple, (in 6, 
green, with reddish spots within). Labellwm large, cucul- 
late, beneath very obtuse in 2; in B less so:—the mouth 
nearly circular, contracted, a little inflexed and quite entire; 
the substance very thick and fleshy, externally pale green 
tinged with purple, internally yellow, and blotched with 
very deep purple. Column and sete as in C. tridentatum. 
A. Flower of var. 8: nat. size.
