The lamina is up to 90 x 33 cm, broadly to narrowly ovate with an acuminate apex with the basal pinnae not reduced, or barely so.[2] The pinnae are up to 33 x 16 cm and form an angle of more than 50° to the rachis. The pinnules are oblong to very narrowly oblong in outline. The rachis becomes glabrous with maturity.[2] Varieties
