Hab. Perak : Scortechini, Maxwell’s Hill! 
Pahang: Kota Glanggi, on limestone rocks ! 
Also occurs in Java and Sumatra ! 
There is a fairly good drawing of this in De Vriese’s illustra- 
tions. It is very dissimilar in habit, and in several other 
points differs from the rest of the genus. The stems are long, 
pendulous, and weak. The racemes are very slender, and 
usually bear several flowers; but these develop one by one at a 
few days’ interval of time. The flowers are pale rose colour, 
deepening into crimson at the apices of the petals and sepals; 
the lip is white with a crimson violet apex; towards the apex 
of the lip are two blunt linear calli. The appendage is linear 
oblong retuse. The pollinia are six in number on pedicels. 
These pedicels are spoon-shaped, broader than the pollinia, 
which are planted at the base of the broad portion and are but 
little longer than it. The discis round. The rostellum is very 
small; shorter indeed than the raised edge of the clinandrium.
