and 2 mm. broad. Lip obovate, acute, simple, about 8 
mm. long and 5 mm. broad, with one strong central, can¬

Pseuderia ramosa seems to be most closely allied to 
P.vanikorensis Ames, a species which occurs in the Santa 
Cruz Islands. The following characters will serve to dis¬ 
tinguish them. 
Pseuderia ramosa 
Lip obovate, about 8 mm. long. 
Petals 3- to 5-nerved, about 10 
mm. long. 
Pseuderia vanikorensts 
Lip elliptic, about 5 mm. long.

Pseuderia ramosa is the first species of the genus to

This is a second collection of Professor Fukuyama’s 
recently described species. Dendrobium nanarauticolum 
belongs to the group of the subgenus Bolbodium which 
is characterized by diphyllous pseudobulbs. Professor 
Fukuyama did not indicate to which species he con-
