Common names:
Frequency:
Status: Native
Description:
Rhizome shortly creeping to semi-erect, up to 5-7 mm in diameter; rhizome scales reddish brown, subentire, apex slowly tapering to a point, up to 7 mm long, margins serrulate. Fronds tufted, erect, coriaceous. Stipe dark brown, up to 25 cm long, subglabrous with few hair-like brown scales near the base. Lamina ovate to lanceolate in outline, up to 24 cm × 10 cm, imparipinnate to 2-pinnate on the base, if bipinnate with 2-5 pairs of lateral pinnules below a slightly larger terminal pinnule. Pinnae narrowly elliptic to lanceolate in outline, up to 5 cm long, apex rounded, cordate to rounded base articulated to a short petiole, glabrous on both surfaces, paler green below, veins hardly visible and anastomosing. Rhachis and secondary rhachises black, shortly pubescent above, glabrous below. Sori marginal, continuous; indusium entire, membranous, continuous.
Notes: Could be mistaken for P. longipilosa or P. doniana. P. longipilosa has free veins, a more stout stipe and a brown indumentum on stipe and rhachis. P. doniana is never 2-pinnate.
