Of California's total plant population, 2,153 species, subspecies, and varieties are endemic and native to California alone, according to the 1993 Jepson Manual study. [4] This botanical diversity stems not only from the size of the state, but also its diverse topographies , climates, and soils (e.g. serpentine outcrops ).
Like other ferns, members of the Marsileaceae produce spores, but not seeds when they reproduce. Unlike other ferns, the spores in this family are produced inside sporocarps. These are hairy, short-stalked, bean-shaped structures usually 3 to 8 mm in diameter [1] with a hardened outer covering. This outer covering is tough and resistant to ...
Invasive species in California, the introduced species of fauna−animals and flora−plants that are established and have naturalized within California. Native plants and animals can become threatened endangered species from the spread of invasive species in natural habitats and/or developed areas (e.g. agriculture, transport, settlement).
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.
Pentagramma triangularis, commonly known as the gold fern or the goldback fern, is a species of fern in the family Pteridaceae, native to Western North America, with highest abundance in the state of California. [2] Its common name "goldback" refers to the light yellow color of the fern's protective coating which inhibits moisture loss.
The spores repel water and have been used as a powder on skin rashes and even on baby bottoms, and to treat wounds. Spores have been used historically as coating for pills, and in the Americas and Europe as fabric dyes. Spores are also highly flammable due to their high content of oil.
