Botanical Description
The rhizome is short or long creeping, slender. The fronds are 4-40cm long and 0.6-2.7cm wide, glaucous green to rich green, often with a characteristic sheen especially in exposed localities. The stipes are 0.5-20cm, dark reddish brown at base, usually becoming stramineous before rachis.
The lamina is linear-lanceolate, pinnatisect-pinnate, 4-40 or more pairs pinnae. The sterile pinnae are oblong-obtuse to somewhat triangular, 3.5-13mm long and 2-6mm wide, papery to coriaceous, adnate with broad bases, margins entire or slightly crenate, often reflexed. The spores are 32.4 x 24.0 micrometer, perine scabrate to microvermiculate or microverrucate, exine smooth, granulate or scabrate.
