Description: |
Rhizome creeping, ending in a thick erect stem of up to 5 cm in diameter; scales brown, linear-attenuate, up to c. 2 cm long, margins entire. Fronds whorled, strongly dimorphic. Stipe up to 10 cm (20 cm) long, densely covered with scales at the base. Sterile lamina 28-45 cm × 5-10 cm, pinnate and oblong-elliptic in outline, apical pinnae overlapping, basal pinnae gradually reduced and spaced apart; pinnae glabrous, oblong, joined onto the rhachis and with rounded to acute apices, margins entire. Fertile lamina a third to half the size of the sterile lamina, narrowly oblong in outline; pinnae narrowly oblong, densely crowded together and often bending forwards. Sori linear, covering the whole length of the fertile pinnae; indusium continuous. |
Notes: | Resembles B. punctulatum and B. australe. B. inflexum has sori that completely cover the underside of the fertile pinnae, the fertile fronds are conspicuously shorter than the sterile fronds, pinnae of the sterile fronds are overlapping at the apex and adnate. |
Derivation of specific name: | inflexum: bent inward, refers to the infolded fertile pinnae at maturity |
