Tectaria decurrens (C.Presl) Copel.

Caudex short, erect; stipe to 50 cm long, winged except in basal 2-10 cm, the wing 5-10 mm wide on each side distally, basal scales 10 mm long, 1.5-2 mm wide at their bases, firm, distal scales narrow; lamina thin, lobed, to 60 cm long, the lobes 2-7 pairs joined by a wing, sterile ones to 7 cm wide, fertile narrower and sometimes with sinuous or irregularly lobulate margins, basal lobes sometimes bilobate; main lateral veins in lobes c. 10 mm apart along the costa, prominent on the lower surface, smaller veins amply anastomosing in sterile fronds, fertile ones with closer main veins and smaller areoles; lower surface of costae and main veins minutely hairy, minute hairs also sometimes present between veins, narrow scales ± abundant on lower surface of rachis and sometimes on costae of lobes (such scales apparently rare in W Malesia); upper surface quite glabrous; sori in a row on each side of main veins in lobes of the frond, also on rachis-wings, on free veinlets in areoles, variably somewhat immersed with corresponding projections on the upper surface; indusia large (crumpled when old), glabrous, round or elliptic, sometimes apparently peltate but more usually attached along a line from the centre to the base; spores spinulose.

It is a tropical plant.
