midrib, the reticulations obsolete; petioles about 2 mm long. 
Very young flowers in axillary, short, few-flowered cymes, the 
pedicels, sepals, and petals ferruginous-pubescent. Fruits glo-

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.
