 basim, in circuitu late ovatum, mucronatum, glabrum; callus 

 pulvinatus, transversus, antice bilobus, ad basim columnae co-

A close ally of Liparis gibbosa (Bl.) Finet, from which it is in 

 part distinguished by the smooth labellum, by the pseudobulbs 

 being less remote from one another, and by subtle differences 

 in the structure and consistency of the flowers which are quite 

 apparent when the two species are compared side by side. In the 

 Javan L, gibbosa the labellum in specimens that I have studied 

 is minutely, although conspicuously, papillose. In both species 

 the labellum is similar in outline and in having the characteris- 

 tic constriction at the sides which gives a pandurate aspect to the 

 lamina when in natural position. It would seem that the Phihp- 

 pine specimens referred to L. disticlia belong here.
