Astrolepis integerrima (Hook.) Benham & Windham

Astrolepis integerrima (Hook.) Benham & Windham. Astrolepis integerrima is a fern in the family Pteridaceae known by the common names hybrid cloakfern and southwest cloakfern. Though widespread through much of northern Mexico and parts of the southwestern and south central United States, it is nowhere common. It is only found on calcareous rocks, cliffs, and canyons in the deserts and similarly dry habitats. Astrolepis integerrima is an allotriploid, a type of hybrid containing all or almost all the chromosomes of two different species.
