Root of long fleshy tomentose fibres. Leaves 1-3, all radical, 3-6 in., elliptic 
or elliptic-lanceolate, acute, many-nerved and trabeculate, primary nerves 3 i 
distinct ; petiole rather longer, embraced at the base by membranous sheaths. Scape 
8-18, slender; sheaths acuminate. Raceme 4-8 in.; bracts convolute, acuminate, 
equalling the ovary; pedicel with ovary decurved ; sepals 1-3 in., greenish, acuminat? 
margins revolute; petals rather shorter, reflexed ; lip as long as the petals, abe 
nate, purple, mottled. Capsule } in., ellipsoid.—There is some little difference in the 
breadth of the lip between the Ceylon and Malayan forms, broader in the former, 
but I do not find that organ to be pubescent in either, or in the Khasian.
