transverse veins numerous, and together with the reticulations and eys- 
toliths conspicuous on both surfaces ; stipules about 0.5 mm long. 
Luzon, Province of Nueva Vizcaya, Mount Dalemdim, at 1500 m elevation, 
Bur. Sci. 8181 Ramos. Allied to P. luzonensis Merr., but distinguished by its 
shorter internodes, and smaller, shorter-petioled, more rigid leaves.

This species has great general similarity to P. scripta Wedd., but has very 
short peduncles, and the leaf-serration extends to the acumen; comparison with 
Indian material shows the following distinct difference in the venation. The 
veins from the midrib in P. scripta are interruptedly thickened, and at about two- 
thirds of the distance to the nerves are united by a somewhat definite though 
rather faint vein nearly parallel to the nerves : in P. luzonensis, the veins are of 
equal thickness or gradually fainter distally, there is no such connecting vein on 
any of the sheets cited except the very doubtful one from Mount Tonglon. 
Endemic.

Of our other species, probably most neatly related to those of the P. melasto- 
moides alliance, but not at all closely.
