Characteristics

Rhizome massive, fronds close; scales c. 10 by 1 mm, rather stiff and straight, often with inflexed edges but not crisped even near apex, entire or nearly so, dull brown; phyllopodia 2-3 cm long. Sterile frond: stipe 10-18 cm, rather thick, grooved deeply on upper surface only; lamina coriaceous, commonly to 35 by 5-6 cm, to 48 by 8 cm or more (80 by 10 cm reported in Java), acuminate, base rather narrowly cuneate and a little decurrent; thin edge pale, narrow, usually reflexed when dry; veins distinct but little prominent; costa rounded and prominent beneath; scales on lamina scattered, very small, stellate, brown. Fertile frond: stipe usually longer than sterile, to 20 cm or more; lamina commonly to 25 by 4 cm, base rather abruptly narrowed, apex short-acuminate.
