different. locality and. slight differences in the vegetative organs 
warrant the belief that it is distinct. The petal-like character 
of the lip was remarkable, but was found in five flowers successively 
examined.

Flowered in the Solléetion of Sir Trevor Lawrence, Bart., 
Burford, Dorking, in February, 1899, having originally been 
obtained from the Hon. Walter Rothschild. It is allied to 
C. purum, Nees, and C€. uncatum, Rolfe, but, among other 
characters, is readily distinguished by the rostellum possessing a 
pair of slender diverging teeth, in addition to the normal antennae. 
‘The flowers are light green, with the inside of the lip buff-yellow.

flowers, those of the latter being described by Dr. Kranzlin 
scarcely 1-5 mm. in diameter.
