298 MR. H. N. RIDLEY—AN ENUMERATION OF 
The spur is porrect as in the rest of the genus, globose almost at 
the base, and then tapering off into a rather long upcurved born 
which is tipped with crimson. The petals and sepals are widely 
spread and of a golden-yellow colour, their bases dotted with 
crimson spots, so that there is a circle of spots allround the 
column and lip. Only a few flowers are open at a time on the 
pendent rbachis in the plants I have seen, but De Vriese’s figure 
gives a number expanded. His plant, however, was evidently a 
very fine specimen. I have seen another plant much like this 
from Manila, with a very much longer lip bifid at the apex.

native of the Philippines.

This is really most closely allied to Saccolabium, but it has the 
long column of Sarcochilus. The lip is not easy to describe. 
There is no distinction between the lateral lobes and epichil, the 
sides are raised and enclose a narrow passage to the spur ; below 
the opening is an ovate acute limb which is evidently the epichil, 
and just above this there is a callus on each side of the channel 
between the two walls formed by the lateral lobes.
