252 MR. HENRY RIDLEY ON ORCHIDEA AND 
Denprosium (§ VirGat®) vinLosuLum, Wall. List, n. 2006. 
D. Lobbii, Teysm. et Binn. in Tijdschr. Nederl. Ind., v. (1853) 
p. 491. 
Hab. Singapore: Bajan, in dry woods! Toas! Kranji!

Kedah: Kedah Peak! At 4,000 feet elevation. 
I have little doubt but that Teysmann’s D. Lobbii is the 
same as Wallich’s plant, as there are specimens quite identical 
with the common species in Lobb’s Herbarium (n. 482). It is 
always terrestrial, growing among dry leaves and in moss, and 
ascending to the tops of the mountains.

An ally of D. pinifolia, Ridl., but differing in its thinner 
glabrous stems, linear channelled leaves, much smaller flowers, 
and different lip. The base of the column is excavate, so as to 
form a nectary. It is epiphytic, growing on trees, at no great 
height from the ground in dense woods.
