Facts About

Slender cliff-brake is found in western New England on high-pH cliffs, or sometimes on roadcuts, or once in Massachusetts in the mortar of a brick wall. It can be distinguished from its close relative purple cliff-brake (Pellaea atropurpurea) by the lack of hairs on the ultimate leaf segments.
