Adiantum jordanii

''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.〔U.S. Department of Agriculture. 2009〕
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''.〔C. Michael Hogan. 2008〕
Each trailing leaf may reach over half a meter in length and is made up of many rounded green segments. Each segment has two to four lobes and it may split between the lobes,〔''Jepson Manual''. 1993〕 the underside of each segment bearing one to four sori.
Adiantum jordanii is a carrier of the fungus-like oomycete, ''Phytophthora ramorum'', which causes Sudden Oak Death. The USDA enforces an import control, focusing intensely on areas (CA, OR, NY in U.S.A.) that are infected with Sudden Oak death. When sold, they must be identified by place of origin and must also be accompanied by a phytosanitary certificate. The USDA warns to not take cuttings from wild specimens.〔U.S.D.A. Import Control Notice〕
Adiantum jordanii, from native plant nurseries, is used in native plant and wildlife gardens.
