Types

Original diagnosis/description

Small leaves with a petiole, lamina narrowly ovate to elliptical, base obtuse to rounded, apex incomplete, obtuse to probably acute with indistinct mucro. Leaf margin irregularly flat crenate. Primary vein strong, secondaries semicraspedodromous, bifurcated in different places, forming narrow arches with each other and with intersecondary veins; tertiary veins usually branching obliquely from the secondary veins and are perpendicular to the primary vein; fine veinlets entering into the tooth sinus from the outer vein arches.

Etymology

Similar to leaf margin and venation comparable with P. coccinea, but outline ovate to elliptical instead of obovate as typical for P. coccinea.
