Discusión taxonómica
Hypolepis melanochlaena seems to be closely related to H. repens, but is distinct by the dark color and glabrous blade surfaces. A specimen from Veracruz (Gómez-Pompa et al. 5460, XAL) has dark blade color and is virtually glabrous, but has minute catenate hairs (to 0.2 mm) at the base of the penultimate segments.
