Description |
Rhizome erect to suberect, up to 90 cm tall, with persistent winged stipe bases, which are surrounded by thick brown roots, forming a caudexlike mass of up to 90 cm in diameter. Fronds tufted, stiff. Stipe up to 60 cm long, pale brown, subglabrous. Lamina up to 2 m, bipinnate and lanceolate in outline. Pinae knifeshaped or narrowly lanceolate in outline, 15-30 x 2.5-5 cm. Pinnules glabrous, linear-oblong in outline, slightly falcate, apex acute, margin crenate to bluntly serrate towards the apex, adnate to the costa, 2.5-4 x 0.5-0.8 cm. Sporangia cover the basal third of the undersurface of the lower pinnae. |
Notes | The distinctive sporangia on the undersurface of the pinnules nearest to the rhachis make this fern very recognizable. |
Derivation | barbara: strange, foreign, as Linneaeus must have looked upon this fern when he first described it. |
