370 MR. HENRY RIDLEY ON ORCHIDEEZ AND 
minatus; discus minutissimus. Stigma grande, ellipticum, 
marginatum. 
Hab. Singapore: on a tree in Dalvey Road, very rare! 
It has also been brought in by dealers from some of the 
other islands. 
This pretty species was first found on a roadside tree in 
Singapore by anative. It is a stout broad-leaved plant, with 
a dense hanging panicle (only one-branched) or a simple 
raceme of chestnut-coloured flowers with a yellow lip. 
The lip in section shows a short ridge on the epichilary 
portion which meets, but is not adnate to, the back of the 
spur; above it on the back of the spur is a very slender forked 
process. This is so delicate that it is very easily overlooked, 
even in a living specimen. 
The clinandrium is elevated in the centre, the pedicel of the 
pollinia overlying this. The dise of the pollinia is so minute 
as to be almost invisible.
