Notes
Possible confusion with D. filix-mas (L.) Schott, 1834, which has few light brown scales on the petiole, dentate pinnules, and lacks a black spot at the junction of the pinnae with the rachis, while D. affinis has abundant reddish-brown scales on the petiole, entire pinnules, and a black spot at the junction of the pinnae with the rachis, visible on the abaxial side.
Possible confusion with D. borreri (Newman) Kinahan, 1856, which has few light brown scales on the petiole, and more or less asymmetrical basal pinnae with dentate or at least lobed first pinnules, while D. affinis has abundant reddish-brown scales on the petiole, and symmetrical basal pinnae with entire pinnules.
