General: Common Maidenhair Fern (Adiantum capillus-veneris) is a black-stemmed, green-leaved fern that one would not expect to find in the desert. The fronds are actually large and pinnately compound, but the individual leaflets are small (1/2 to 3/4-inch across), fan-shaped, and notched at the end.

Common Maidenhair is an uncommon component of vegetation communities in shaded wet areas such as seeps and springs in the Lower Sonoran (Creosote-Bursage Flats), Upper Sonoran (Mojave Desert Scrub and Pinyon-Juniper Woodland), and Transition (Yellow Pine Forest) life zones. Look for this species in damp soil under boulders and on shaded cliffs around seeps and springs.

Family: Brake (Pteridaceae).

Other Names: Maiden-Hair Fern
