In the size and outline of the fronds, and the length of the 

 peduncle and spike, this species bears a strong resemblance to the 0. 

 ellipticum of Hooker and Greville. But the costa or midrib in the 

 present plant is much less prominent, and the meshes of the venation 

 are more elongated. The stipe is also longer.

0. pygmceum ; radice fibrosa ; spica caulina; fronde subcoriacea elliptico- 

 lanceolata basi attenuata; venis crebre reticulatis.
