Description
Rhizome without the scales 5 mm in diametre (with scales c. 10), not white waxy (D. multidentata Rhizome). Scales brown without pale border, narrowed evenly towards the apex, often curling backward, not bearing multiseptate hairs, lacking marginal setae or teeth or toothed, basifixed with cordate base and much overlapping lobes, 6 mm long. Stipes pale or dark brown, adaxially grooved, 17-25 cm long, glabrous or with few scales. Lamina compound (D. multidentata Leaf), tripinnate, deltoid and broadest towards base, glabrous, 30-45 cm long by 17-34 cm broad, not or slightly dimorphous. Longest petiolules 8-10 mm long. Pinnae linear-triangular. Longest pinnae 10-19 cm long by 6-9 cm broad. Pinnules of at least the larger pinnae anadromous, narrowly ovate. Longest pinnules 40-70 mm long by 15-30 mm broad. Ultimate leaflets linear oblong, lobed halfway towards midrib. Ultimate segments or lobes obtuse or acute without a tooth, 2-4 mm long by 1 mm broad (often shallowly lobed). Leaf axes, at least rachises, hairy. Hairs 0.1-0.2 mm long. Veins in sterile ultimate lobes simple or forked, not reaching the margin. False veins not present. Sori separate, frequently single on a segment at the forking point of veins or at the bending point of a vein.
