384 MR. HENRY RIDLEY ON ORCHIDEZ AND 
Locality uncertain. I received this froma tree in the garden 
of Mr. Rauch in Singapore. The plants were not known to 
have been introduced, but it is quite possible that they came 
originally from Sumatra. Bulbophyllum Ephippianthus was 
growing with it. 
The habit of the plant is that of D. filiformis, mihi; but the 
bracts are longer and recurved, the flower has the sepals and 
petals of a fine dark red, the lip is quite glabrous, except the 
pubescent callus, and hastate-cordate in shape, hardly saccatc 
at all. It is of a bright orange yellow with reddish bars on the 
sides, and some red spots on the claw. The column is of a red 
orange. It is the prettiest species I have yet seen.

A very common plant usually to be found on orchard or 
roadside trees. It varies a good deal in size of pseudo-bulb, 
breadth of foliage, and development of panicle. I once found a 
quantity growing in tufts of grass on the sea-shore at Kwala 
Pahang. It is called “ Angrek Darat” (sea-shore orchid), 
“ Sakat Bawang ” (onion-epiphyte), and “‘ Sakat Ubat Kapialu” 
(epiphyte, medicine for headache) by the natives. The roots 
and leaves are boiled to make a drink for fever.
