Stems long-creeping, branching, 2.5--4 mm diam., pubescence brown. Leaves 9--60 dm. Petiole straw-colored to reddish brown, 2--4(--6) dm, glabrous or pubescent, bearing prickles; primary pinnae similarly pubescent. Blade deltate, 3--4-pinnate-pinnatifid, lateral divisions opposite or nearly so, (2.5--)4--15 × 1.2--6 dm. Rachis nearly glabrous or glandular-pubescent, with prickles. Ultimate segments spreading, elliptic to lanceolate or oblong-elliptic, pinnatifid, 4--9 × 7 mm, abaxially paler, somewhat papery, nearly glabrous to glandular-pubescent, lobes rounded. Veins simple to 1-forked, ending just short of margins. Sori in sinuses of ultimate segment divisions, reniform to semicircular or appearing circular at maturity. Indusia formed from thin, recurved flap of blade tissue, sometimes obscured by sporangia when mature. 2 n = 208.

Hojas hasta 4 m, con crecimiento continuo, erectas a escandentes; pecíolo pardo, pardo-amarillento o pajizo, espinoso, moderada a escasamente peloso o glabrescente; ambas superficies de la lámina escasa a moderadamente pelosas a lo largo de las nervaduras, glabras entre las mismas, los tricomas cateniformes, hialinos; márgenes de la lámina sin cilios; costas de los penúltimos segmentos bordeadas por una cresta no decurrente; raquis espinoso, pardo, pardo-amarillento pajizo, recto (no flexuoso) basalmente, escasa a moderadamente peloso; nervaduras no terminando en emarginaciones poco profundas; indusio 0.1- 0.3 mm de ancho, escarioso, sin cilios; 2n=104.

Esta es una de Hypolepis más comunes y con más amplia distribución en Mesoamérica. Hypolepis mexicana se ubica aquí en sinonimia debido a que el lectotipo designado por Smith posee un indusio entero a sólo ligeramente eroso (Smith, 1981). El isosintipo en US, sin embargo, posee indusios evidentemente ciliados y calificaría por tanto para H. blepharochlaena. Parece ser que la colección tipo, Liebmann 2751, estaba mezclada.
