mm. broad. Lateral sepals linear-lanceolate, fleshy, acute, 
arcuate, 8- (5-) nerved, about 18 mm. long and 4 mm. 
broad. Petals linear, acute, 3-nerved, about 12 mm. long 
and 2 mm. broad. Lip oblong-ovate, obtuse, simple, with 
one strong median callus which divides into two carinae 
at the base and four smaller keels which converge to the 
main keel toward the base, 8-10 mm. long and about 4-5 
mm. broad. Column of the genus. 
Pseuderia platyphyllais closely allied to P. diversifola 
J.J.Sm.,a species which was described from Dutch New 
Guinea. The present species may be distinguished by 
the generally narrower leaves, by the oblong-ovate (not 
rhomboid) lip and by the fact that the lip is strongly re- 
flexed near the base and not evenly reflexed for most of 
its length.
