Description |
Rhizome shortly creeping to suberect, c. 5 mm in diameter; rhizome scales linear-lanceolate in outline, margin entire, up to 12 mm, rust-coloured. Fronds monomorphic, tufted, erect, 7-32 cm long, herbaceous to coriaceous, shriveling up during the dry winter months. Stipe 2.5-20 cm long, purple-dark brown to black, with short, fine white hairs and with scales similar to those of the rhizome at the base. Lamina 2-pinnate to 3-pinnatifid on the basal pinnae which are not reduced in size, broadly ovate, pentagonal to almost deltate in outline, up to 12 × 6 cm; pinnae 11-14 pairs, lanceolate in outline, upper surface pilose, lower surface sparsely covered with long, soft white hairs, turning rustcoloured with age, margins subentire; rhachis dark brown. Sori marginal, discrete at first but continuous when mature; indusium continuous or discontinuous, ciliate, membranous. |
Notes | Could be confused with C. eckloniana which has shiny golden-brown scales along the costae and costules, and basal pinnae that might be slightly reduced. The lower surface of the lamina of C. inaequalis is densely covered with short hairs. |
