Polypodium cambricum | |
Polypodium cambricum, the southern polypody, [1] limestone polypody, [2] 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. [3]
Perennial. Rhizome elongate, often above ground, densely covered with rusty scales. Fronds distich, 5–30 centimetres (2.0–11.8 in), glabrous, deltoid in outline; petiole yellowish green, shorter than the pinnatipartite limb. Segments 5-28 on each side; margin dentate, marked with a strong midrib. Sori round, 2–4 millimetres (0.079–0.157 in) in diameter, orange-yellow, arranged on each side of the midrib of segments. The fruits bloom from February to July.
This species has been widely known by the more apt name P. australe Fée. However, since Linnaeus did mention the species, albeit in the aberrant cambricum-form, that name must have priority.[ citation needed ]
Polypodium is derived from the Greek Polus, many, and podion, small foot, since the rhizome bears numerous roots. The specific epithet cambricum means "Welsh", [4] from the Latinized form of Cymru , the Welsh name for Wales.
Australe comes from the Latin auter, wind of the south, for in Europe, this species grows largely in the Mediterranean Basin. [5]
Two cultivars have received the Royal Horticultural Society's Award of Garden Merit:
Pleopeltis polypodioides, also known as the resurrection fern, is a species of creeping, coarse-textured fern native to the Americas and Africa.
Nephrolepis exaltata, known as the sword fern or Boston fern, is a species of fern in the family Lomariopsidaceae. It is native to the Americas. This evergreen plant can reach as high as 40–90 centimetres (16–35 in), and in extreme cases up to 1.5 metres. It is also known as the Boston sword fern, wild Boston fern, Boston Blue Bell Fern, tuber ladder fern, or fishbone fern.
Polystichum munitum, the western swordfern, is an evergreen perennial fern native to western North America, where it is one of the most abundant ferns in forested areas. It occurs along the Pacific coast from southeastern Alaska to southern California, and also inland east to southeastern British Columbia, northern Idaho and western Montana, with disjunctive populations in northern British Columbia, Canada; the Black Hills in South Dakota, United States; and Guadalupe Island off of Baja California, Mexico. Western swordfern is known to have locally naturalized in parts of Great Britain and Ireland.
Dryopteris filix-mas, the male fern, is a common fern of the temperate Northern Hemisphere, native to much of Europe, Asia, and North America. It favours damp shaded areas in the understory of woodlands, but also shady places on hedge-banks, rocks, and screes. Near the northern limit of its distribution it prefers sunny, well-drained sites. It is much less abundant in North America than in Europe. The plant is sometimes referred to in ancient literature as worm fern, reflecting its former use against tapeworm.
Athyrium filix-femina, the lady fern or common lady-fern, is a large, feathery species of fern native to temperate Asia, Europe, North Africa, Canada and the US. It is often abundant in damp, shady woodland environments and is often grown for decoration.
Polystichum aculeatum, the hard shield-fern, is an evergreen fern native to Europe. It is most abundant in upland regions of the British Isles and western France, where it benefits from the combination of mild winters and moist summers, but also occurs more locally across most of Europe except northern Scandinavia, northern Russia; in the Mediterranean region it is confined to high altitudes. It grows on steep slopes in woodlands. it is sometimes considered an indicator of the presence of ancient woodlands.
Polystichum setiferum, the soft shield fern, is an evergreen or semi-evergreen fern native to southern and western Europe. The stalks and most midribs are coated with attractive cinnamon-brown scales. The Latin specific epithet setiferum means “with bristles”.
Phlebodium aureum is an epiphytic fern native to tropical and subtropical regions of the Americas.
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.
Polypodium glycyrrhiza, commonly known as licorice fern, many-footed fern, and sweet root, is a summer deciduous fern native to western North America, where it is found in shaded, damp locations.
Asplenium trichomanes, the maidenhair spleenwort, is a small fern in the spleenwort genus Asplenium. It is a widespread and common species, occurring almost worldwide in a variety of rocky habitats. It is a variable fern with several subspecies.
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.
Polypodium californicum is a species of fern known by the common name California polypody.
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.
Diplazium australe, commonly known as the Austral lady fern, is a small fern occurring in eastern Australia, New Zealand and Norfolk Island. The habitat is moist shaded areas, often occurring in rainforest.
Woodwardia radicans, the chain fern, European chain fern or rooting chainfern, is a species of fern in the family Blechnaceae, mainly found in Macaronesia and southwestern Europe, but is also found in southern Italy and Crete. Growing to 1.8 m (6 ft) tall by 2 m (7 ft) broad, it is evergreen with arching fronds. The pinnae have curved, finely-toothed segments. The plant derives its common name from the linked sori on the undersides of the fronds.
Dryopteris aemula, the hay-scented buckler-fern or hay-scented fern, is a species of perennial leptosporangiate fern.
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.
