Discusión taxonómica
Besides the dull abaxial surfaces and the wide, erose to ciliate indusia, which distinguish it from Hypolepis repens, this species generally occurs at higher elevations, (1780–)2150–2450 m, whereas H. repens occurs between 450 and 1250(–1550) m. The non-glandular, almost glabrous adaxial blade surfaces and long (1–1.3 mm), wide (0.8–1 mm) indusia separate H. blepharochlaena from H. microchlaena. Specimens of H. blepharochlaena have often been mistakenly named H. mexicana (here regarded as synonymous with H. repens), but the type material of the latter has indusia not noticeably broad nor ciliate and was collected at 4000–5000 ft (1250–1550 m).A
