Characteristics

Rhizome short; scales thin, light brown, 5-7 by 2-3 mm, edges with short hairs; phyllopodia to 2 cm long. Sterile frond: on young plants widest above middle with ± broadly rounded apex and gradually narrowed base, with a rather persistent fringe of spreading scales 1.5-2 mm long all along edge of lamina; lamina to c. 20 by 4 cm; on mature plants with stipe 10-15 cm, persistently scaly as rhizome, lamina rigidly coriaceous, to 25 by 3.2-4.5 cm, widest at or a little above middle, sides parallel for most of their length, narrowed rather abruptly at 4both ends, base a little decurrent, apex bluntly pointed or rounded; pale thin edge distinct; veins obscure; costa slightly raised on lower surface; small scales on lamina light brown, to 1 mm long, narrow with hairs near base, near edge of lamina on both surfaces broader scales 1 mm long ± persistent. Fertile frond: stipe 17 cm; lamina to 26 by 3.5 cm.
More
Rhizomes shortly creeping, 3-4 mm thick, densely scaly; scales brown, ovate-lanceolate, ca. 5 mm, membranous, margin entire or slightly ciliate, apex acuminate.
