Description: |
Rhizome widely creeping, c. 2 mm in diameter; rhizome scales brown, appressed, lanceolate, slightly ciliate. Fronds closely spaced or frequently tufted at the end of the rhizome, herbaceous, glabrous, arching. Stipe up to 35 cm long, dark brown to black, shiny, glabrous. Lamina 2-4 pinnate, broadly ovate-deltate in outline, 30 × 25 cm. Rhachis and stalks black, shiny, glabrous. Pinnules deciduous, 1.5 × 2 cm, semicircular to obdeltate, lobed on the outer margin, veins ending in the sinuses of the lobes of the outer margin. Sori 1-6, on the undersurface of the pinnules along the outer margin, indusial flap oblong to crescent shaped, up to 2.5 mm long, glabrous, sometimes surrounded by some yellow powder. |
Notes: | May be confused with A. capillus-veneris which has the veins ending in the teeth of the marginal serrations. A. raddianum has much smaller pinnules and almost circular shaped sori. The pinnules of A. poiretii are also deciduous. |
