Description: |
Rhizome erect to prostrate, up to 15 mm in diameter; rhizome scales lanceolate, brown with dark central stripe, up to 3 mm long, ciliate. Fronds tufted, arching, slightly coriaceous. Stipe up to 60 cm long, strawcoloured to dark brown, glabrous. Lamina up to 1 × 0.8 m, ovate in outline, deeply 2-pinnatifid, basal pinnae basiscopically developed. Pinnae narrowly lanceolate, pinnatifid; ultimate lobes narrowly linear, apices rounded, margins entire; veins free, no veins anastomosing below the sinus; glabrous on both surfaces, single spine present along the costa at the junction of the costules on the uppersurface only. Rhachis glabrous, smooth. Sori linear, continuous, marginal; indusia entire, membranous. |
Notes: | Can be confused with Pteris Catoptera of which the lamina has a more membranous texture, it also has spines on the costules and costae on the upper surface of the lamina. Pteris dentata has ultimate lobes with serrate-dentate margins. |
