Adiantum jordanii C. Muell. |
Adiantum jordanii is a perennial species of maidenhair fern known by the common name California maidenhair.[1]
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.[2]
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,[3] the underside of each segment bearing one to four sori.
WARNING Adiantum jordanii is a carrier of Sudden Oak Death which is caused by the fungus-like oomycete, Phytophthora ramorum. 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. Do not take cuttings from wild specimens.[4]
Adiantum jordanii, from native plant nurseries, is used in native plant and wildlife gardens.
