About Polypodium californicum Kaulf.
Polypodium californicum Kaulf. anchors itself with a scaly rhizome. It produces oval to triangular leaves that can grow up to 70 centimetres (28 inches) long and 20 centimetres (7.9 inches) wide. Each leaf consists of many dull-pointed lance-shaped segments; these segments can be thin, firm, or somewhat fleshy, and have lightly serrated edges. The underside of each leaf segment holds a double row of flattened or sunken sori, which contain the fern's spores.
