midrib, the reticulations obsolete; petioles about 2. mm long.

DiNAGAT, Bur. Sci. 35186 Ramos & Pascasio, May 12, 1919, 

 in forests at low altitudes. 



A species manifestly allied to Popowia polyandra (Presl) 

 Merr., which in turn is perhaps not specifically distinct from 

 the Malayan P. pisocarpa Endl. The present species is strongly 

 characterized by its narrow, lanceolate, slenderly acuminate 

 leaves.
