hairs always present on lower surface of costae, costules and veins, variable, sometimes to 1 mm long, few or none between veins; hairs on upper surface between veins abundant, at least 1 mm long (to 1.5 mm);
Asia-Tropical: New Guinea present, Solomon Islands present
Malesia: widely in New Guinea (only the type from the West); Solomon Islands.
The types of Pleocnemia membranacea var. novoguineensis and Tectaria gymnocarpa both have fewer and shorter hairs on the abaxial side of rachises than most other specimens and fewer thick hairs between veins on the upper surface; they are thus nearer to T. kingii.
