 monstruosa Blume Bijdr. 395. O. monstruosa is the largest of the 

 caulescent species so far known to be natives of the Philippine 

 Islands. The stems attain a height of 2 dm. or even more, and 

 are completely concealed by the sheathing bases of the leaves. 

 In the Philippine material examined each stem bears from five 

 to seven leaves ± 5 cm. long. The labellum of this species is sub- 

 cordate. O. hastata Schltr. from Celebes is a near ally, but in that 

 species the labellum is subtridentate.
