Notogrammitis heterophylla

Rhizome short and coarse, densely covered with brown scales with thickened cell walls; roots numerous, wiry. Fronds crowded, erect or pendent, variable in size and shape (even within the one plant), 5–25 cm long, firm in texture; stipe short, winged, scaly at base, glabrous above or rarely with a few hairs. Lamina pinnate or pinnately-lobed, rarely simple when small. Pinnae uneven in length, obliquely angled to rachis, linear to oblong; margins entire, irregular or with blunt, triangular to oblong, forward-pointing lobes; bases broadly decurrent; lateral veins obscure but free. Sori oval, in single row on each side of midvein, slightly sunken, usually one per lobe.
