California Polypody

Polypodium californicum Kaulf.

R. M. Lloyd and F. A. Lang (1964) recognized two cytotypes within Polypodium californicum . The tetraploid has proved to be an allopolyploid involving P . californicum and P . glycyrrhiza and is treated here as a separate species, P . calirhiza , following S. A. Whitmore and A. R. Smith (1991). Polypodium californicum can be confused with P . calirhiza , but it usually can be distinguished by blade shape, venation, spore size, and geographic distribution. D. S. Barrington et al. (1986) reported that spores of northern populations of P . californicum can be as large as those of P . calirhiza , but the former species has veins forming more areoles per segment than does the latter.

Polypodium californicum

provided by wikipedia EN

Polypodium californicum is a species of fern known by the common name California polypody.

It is native to Baja California and California, where it grows along the coastline as well as in moist spots in coastal foothills and mountain ranges in the southern part of its distribution.

Description

This polypody anchors with a scaly rhizome. It produces oval to triangular leaves up to 70 centimetres (28 in) in length and 20 centimetres (7.9 in) in width. Each leaf is made up of many dull-pointed lance-shaped segments which may be thin or firm or somewhat fleshy, and have lightly serrated edges. The underside of each leaf segment is lined with a double row of flattened or sunken sori, which contain the spores.
