the shape of the leaves is rather different, by the construction of the flower. 

 The shape of the labelium, saccate and connate at its base to the stami- 

 nodes, is almost identical with that of G. longiflora. Wall. 



But while in G. longiflora the cells are longer than the connective, 

 here the connective is a little prolongated above the cells., whereby the 

 theory of Ridley about the useless of this characteristic is once more 

 incontestably proved. 



The small spurs at the base of the cells have some resemblance to 

 those described by Gagnepain in one or two species of Hitcheniopsis, a 

 group which seems to be more or less intermediate between Curcuma and 

 Gastrocfiilus.

By the construction of the flower and axillary inflorescence this species 

 is very similar to 0. angustifoliuin, the stamen with the spurred thecae is 

 quite identical, only a litle smaller. The spike is more slender and not 

 branched at the base. The habit however is very different.
