Rhizome dorsiventrally flattened, 1.8-3 by 1.5-2.6 mm thick, brown; phyllopods 4-9 cm distant. Anatomy: vascular strands 6-9, with dark bundle sheaths, sclerenchyma strands few (3-11). Rhizome scales inserted evenly, persistent, densely set, squarrosely spreading, pseudopeltate, monomorphic, deltoid, 3-4.7 by 0.8-1.1 mm, index 3.5-4.3, basal auricles rounded, margin sparsely set with glands, base irregularly dentate, acumen finely dentate, apex filiform, nearly entire, cell walls clathrate in the acumen, not thickened in the basal auricles, superficial hairs absent. Fronds pinnate, stipe 1.1-1.8 mm thick, 0.5-0.8 as long as the lamina, glabrous; lamina 7-19 by 4-14 cm, index 1.3-1.7, widest at the base; pinnae articulate, sessile to shortly petiolate, 4.5-9 by 0.6-1.5 cm, index 6-7.5, base cuneate to shortly angustate, margin entire to serrate, more strongly towards the apex, apex acuminate; basal pair 1.3-2.5 cm distant from next pair and equally long, sometimes somewhat deflexed, apical segment conform, shorter to longer than longest pinnae, usually more longly acuminate. Venation: areoles uniserial, marginal veinlets up to 1/5 as long as the areole, simple. Indument: 2-celled glandular hairs present, acicular hairs absent, scales deciduous. Sori uniserial, medial to marginal, superficial, 1.6-2 mm diam., receptacular scaly paraphyses persistent, sometimes peltate, clathrate, 210-320 by 140-210 µm, 2 or more cells wide. Sporangia glabrous. Spores yellow, cristate, with long polar ex-crescences.
