Description |
Rhizome creeping, c. 1-3 mm in diameter; rhizome scales pale to dark reddish brown, lanceolate in outline, with a long drawn out point, up to 2.5 mm long, margins entire. Fronds spaced 1-3 cm apart, erect, herbaceous, glabrous. Stipe brown, shiny, up to 36 cm long, glabrous except for a few scales near the base, grooved. Lamina up to 48 × 22 cm, imparipinnate, roughly oblonceolate in outline; fresh smelling lightly of almonds when crushed. Pinnae 7.5-22 × 0.4-2.5 cm, narrowly oblong-lanceolate in outline, shortly petiolate, base unequally cuneate, apex shortly tapering to slightly rounded, margin entire to shallowly lobed, veins forming 1-2 rows of areoles along each side of the costa, venation anastomosing. Rhachis sharply bi-angular. Sori linear, continuous along the fertile pinnae; indusium linear, semitransparent, opening outwards, 0.3-0.5 mm wide. |
Notes | Might superficially look a bit like Pteris cretica which has a shortly creeping rhizome with tufted fronds, pinnae with toothed margins, free veins and an indusium that opens inwards. Pteris cretica does not have a faint almond smell. |
