Fern Canyon is a canyon in the Prairie Creek Redwoods State Park in Humboldt County, California, western United States. The park is managed in cooperation with other nearby redwoods state parks and Redwood National Park. It is named for the ferns growing on the 50-foot (15 m) high walls, through which runs Home Creek. Fern Canyon is recognized as a World Heritage Site and an International Biosphere Reserve.
Phlebodium aureum is an epiphytic fern native to tropical and subtropical regions of the Americas.
Polypodium calirhiza is a species of fern in the polypody family. Its common names include nested polypody and habit polypody. It is found in California and Oregon in the U.S., and several states of Mexico: Colima, Jalisco, Mexico State, Oaxaca, and Veracruz. The leaflets on each leaf are broad and oval-shaped, coming to a dull point. This fern is sometimes epiphytic.
Polypodium vulgare, the common polypody, is an evergreen fern of the family Polypodiaceae. Polypodium vulgare is an allotetraploid species, believed to have arisen by chromosome doubling of a sterile diploid hybrid between two ferns which are not known in Europe. The fern's proposed parents are the northern Asian and northern North American Polypodium sibiricum and western North American Polypodium glycyrrhiza. Biochemical data point to a species from eastern Asia as the second possible parent. The name is derived from poly (many) and pous, podos . Polypody has traditional uses in cooking for its aroma and sweet taste, and in herbal medicine as a purgative and vermifuge.
Dudleya stolonifera is a succulent plant known by the common name Laguna Beach liveforever or Laguna Beach dudleya. This is a rare plant which is endemic to the coastline of Orange County, California. It is known from only about six populations in the vicinity of Laguna Beach, totaling about 30,000 individuals. It is federally listed as a threatened species of the United States.
Geranium californicum is a species of Geranium known by the common name California cranesbill. It is endemic to California, where it grows in the Sierra Nevada and coastal ranges in the southern part of the state.
Polypodium virginianum, commonly known as rock polypody, rock cap fern, or common polypody, is a small evergreen species of fern native to the Eastern United States and Canada. It generally grows on rocks and occasionally on tree roots in nature.
Ophioglossum californicum, known by the common name California adder's tongue, is an uncommon species of fern in the family Ophioglossaceae.
Pediomelum californicum is a species of flowering plant in the legume family known by the common name California Indian breadroot. It is endemic to California, where it grows in the chaparral and woodlands of the coastal mountain ranges. It is a perennial herb with no stem or a short stem that is mostly underground, leaving the plant at ground level. The compound leaves are each made up of five to seven oval leaflets which may be nearly 3 centimetres long. The inflorescence is a raceme of several blue or purple pealike flowers each about one centimetre long. The fruit is a hairy oval beak-tipped legume pod up to one centimetre long containing smooth kidney-shaped seeds.
Polypodium hesperium is a species of fern known by the common name western polypody. It is native to western North America from British Columbia to California, and the Rocky Mountains to northern Mexico, where it grows in rocky habitat types.
Polypodium scouleri is a species of fern known by the common names leathery polypody, Scouler's polypody, coast polypody and leather-leaf fern. It is native to coastal western North America from British Columbia to Guadalupe Island off Baja California. It is a plant of the coastline, growing in cracks on coastal bluffs, in oceanside forests, beach dunes, and similar habitat. It is often affected by heavy fogs and sea spray. This polypody anchors with a waxy, scaly rhizome. It produces triangular or oblong leaves up to 85 centimeters in maximum length and 8 cm width. Each leaf is made up of many round-tipped linear or oblong segments which are usually stiff and leathery in texture and edged with shallow, rounded teeth. The underside of each leaf segment is crowded with rounded sori each up to half a centimeter wide. The sori contain the spores.
Polystichum californicum is a species of fern known by the common name California sword fern. It is native to western North America from British Columbia to California, where it occurs in the coastal mountain ranges and the Cascade Range through the Sierra Nevada. Its habitat includes forest understory and open rocky slopes. This fern produces several arching or erect leaves up to a meter long. Each lance-shaped leaf is made up of many sharp-toothed segments. The undersides bear rounded sori which contain the spores. This fern arose as a hybrid between other Polystichum species and readily forms hybrids of its own.
Ribes californicum, with the common name hillside gooseberry, is a North American species of currant. It is endemic to California, where it can be found throughout many of the California Coast, Transverse, and Peninsular Ranges in local habitat types such as chaparral and woodlands.
Polypodium cambricum, the southern polypody, limestone polypiody, or Welsh polypody, is a species of fern in the family Polypodiaceae, native to southern and western Europe where it grows on shady rocks, near the coasts of the Mediterranean Basin and in the mountains of Atlantic Europe. It is a spreading, terrestrial, deciduous fern growing to 60 centimetres (24 in) tall, with pinnate fronds. The sori are yellow in winter.
The Truttman Sink is an earthflow within the Humboldt Lagoons State Park, along the coast of Humboldt County, California. It is located between Trinidad to the south and Orick to the north. It deposits materials into the northern end of Big Lagoon and the Pacific Ocean, especially during periods of heavy rain. The soil characteristics, geology, and vegetation along the slope of this mass-wasting feature suggest a combination of an earthflow movement and a rotational slump.
Polypodium is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The genus is widely distributed throughout the world, with the highest species diversity in the tropics. The name is derived from Ancient Greek poly (πολύ) "many" + podion (πόδιον) "little foot", on account of the foot-like appearance of the rhizome and its branches. They are commonly called polypodies or rockcap ferns, but for many species unique vernacular names exist.
Polypodium amorphum is a species of fern with the common name irregular polypody, which grows near the northwest coast of North America.
