This occurs in great abundance in open country usually near 
the sea. On Pulau Selitar (a very small island in the Johore 
Strait) it clambers over the thickets, sending down a dense 
curtain of roots.

This usually grows straggling over rocks by the sea, and 
produces abundantly its horizontal panicles of innumerable 
cinnabar red flowers. It flowers every two or three months, 
and lasts long in bloom. 
The natives call it “Poko Api-Api Sesudu.? ‘“ Api-Api” 
signifies a parasite, especially a Loranthus. Suduk (Sesuduk is 
Suduk-Suduk) is a spoon or a kris, possibly referring to the 
shape of the lip. The whole flower is of a dark cinnabar red 
except the white calli, a white spot at the base of the mid-lobe 
and a yellow crest to the anther. The lip is pinched in at the 
upper part of the spur, so that the two lateral lobes meet, leaving 
only a narrow slit as an entrance. The spur is dilated at the 
apex and full of nectar, a very different arrangement to that of 
the other species, which have an open spur narrowest at the 
apex without any nectar. The pollinia are elliptic, the caudicle 
oblanceolate narrowed in the middle, and the gland ovate blunt 
and rather large. The rostellum projects a little from the 
clinandrium floor; it is thin, and shortly bifid. There is @ 
raised lump in the middle of the clinandrium.
