Stems 10—18 in. narrowed at the base, as thick as a goose-quill, green ; inter- 
nodes 2—11 in., terete, lowest sheathed; nodes discoloured ; branches elongate, with 
short brown sheaths at the very slender base. Leaves not seen, probably occurring 
only in a very young state of the plant. Peduncle l—i in., slender, with very short 
imbricating sheaths at the base, 2—4-fld.; pedicel with ovary $ in.; flowers 4-% in. 
long. Sepals subfaleate ; petals 3-nerved, as long as the sepals, green; lip nearly 
twice as long as the sepals, Anther conical. 
A singular species, leafless in all the specimens I have seen, as well as in the drawing, though 
probably leaves are to be found in the young state of the plant; and are, as in its near ally 
D. herbaceum, Lindl. of the Deccan peninsula, very eaducous. The lip, which is described as 
cuneiform and straight, and which appears to be so in dried specimen, is here represented as 
deflexed beyond the middle. i 
The drawing here reproduced is inscribed “D. lingusforme Par. mss, Tenasserim Province, 
brought from Moulmein, 3rd February 1866. Drawn by Gopal, 15th February 1866. 1. Anderson."
