Species

Pteridophytes > Polypodiales > Aspleniaceae > Asplenium

Characteristics

Rhizome short-creeping, up to 7 mm in diam., with tufted fronds and dark brown, narrowly lanceolate scales, tapering to a long hair-point, up to 12 mm long, entire. Fronds tufted, erect to arching, up to 160 mm long. Stipe dark brown, glabrous at maturity, up to 230 mm long, scaled. Lamina 1-or 2-pinnate, linear-lanceolate, up to 280 x 90 mm, with up to 10 pinna pairs. Pinnae coriaceous, broadly obcuneate, becoming increasingly more pinnatifid towards base; basal pinnae pinnatifid into distinct obcuneate pinnules; apices acute to acuminate. Pinnules petiolate, apices irregularly serrate to incised, glabrous on both surfaces except for small, blackish, twisted scales near lobe bases along the costae and on rachis. Sori linear, up to 12 mm long. Indusium linear, entire.
