About

Adiantum jordanii is a perennial species of maidenhair fern, in the Vittarioideae subfamily of the Pteridaceae. The species is known by the common name California maidenhair.

It is native to California and Baja California. A. jordanii is found in the southernmost part of its range in Baja California with such flora associates as Mimulus aridus and Daucus pusillus.

Uses

Ohlone people used the plant as a decoction to treat stomach ailments, as a blood purifier, for "pain below the shoulders", and to aid placental expulsion. In the early 1900s, it was reported that in Salinan land, indigenous people boiled the plant into a tea and consumed it to aid difficult childbirths, induce menstruation, stop hemorrhage, and for the liver.
