Closely allied JT. pauciflora WILLD.; but, as far as is concerned the descrip- 

 tion of the same species given in BENTH. Fl. Hongk. p. 379, our plant is distinctly 

 different from the Hongkong plant in having outer wingless perianth-segments 

 and inner unguiculate hood-formed ribless segment which is much thinner and 

 hyaline. X. pauciflora has " perianth-segments 2 outer narrow and acute, the 

 keel winged ; the third broad, but with a rather stiff and prominent midrib."
