Species

Characteristics

Rhizome widely creeping, dorso-ventrally flattened, up to 8 mm in diam., with 2 rows of alternating phyllopodia up to 4 mm long, with reddish brown scales that are blackish at point of attachment, narrow-lanceolate, peltate, with short outgrowths formed by projections of 2 adjacent cells, up to 6 x 1 mm. Fronds articulated to short phyllopodia, up to 1.1 m long. Stipe firm, adaxially convex with dorso-lateral ridges, initially sparsely scaled, glabrous later, up to 380 mm long, up to 3 mm in diam. Lamina up to 4-pinnate, broadly ovate to deltoid, up to 750 x 380 mm. Pinnae, pinnules, and segments petiolate; alternate and widely spaced, acroscopically developed; segments herbaceous, lanceolate, glabrous, up to 40 x 18 mm, 1-pinnate to pinnatifid. Sori mostly borne on distal part of lamina, at ultimate forking of veins, lamina generally extending into a tooth at both sides of sorus, the outer tooth mostly longer than the inner. Indusium pouch-shaped, entire.
