Hoot 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 in- 

 distinct ; petiole rather longer, embraced at the base by membranous sheaths. Scape 

 8-18, slender ; sheaths acuminate. Baceme 4-8 in. ; bracts convolute, acuminate, 

 equalling the ovary; pedicel with ovary decurved ; sepals - in., greenish, acuminate, 

 margins revolute ; petals rather shorter, reflexed ; lip as long as the petals, acumi- 

 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.
