The rainy season came late this year. After a shower, certain crunched-up ferns expanded to look more fernlike:

This one had impressive scales on the pinnae's undersurfaces:

In it's dried-up state, I'd been assuming this was a Hybrid Cloakfern, Astrolepis integerrima, but now I see this fern's lobes are deeper cut than the Hybrid's. With the help of iNaturalist's user "najera_tutor," this fern appears to be ASTROLEPIS SINUATA, in English called the Wavy Scaly Cloakfern.

Astrolepis sinuata is distributed from the southwestern US south through the dry Mexican uplands into western South America. In our area it's described as inhabiting limy or basaltic soils in canyons, scrub, grasslands and upland forests.
