Fiddlehead Fern
Fiddleheads or fiddlehead greens are the furled fronds of a young fern, harvested for use as a vegetable. Left on the plant, each fiddlehead would unroll into a new frond ( circinate vernation). As fiddleheads are harvested early in the season before the frond has opened and reached its full height, they are cut fairly close to the ground. Fiddleheads contain a compound associated with bracken toxicity. The fiddlehead resembles the curled ornamentation (called a ''scroll'') on the end of a stringed instrument, such as a fiddle. It is also called a crozier, after the curved staff used by bishops, which has its origins in the shepherd's crook. Varieties The fiddleheads of certain ferns are eaten as a cooked leaf vegetable. The most popular of these are: * Bracken, ''Pteridium aquilinum'', found worldwide (Toxic if not cooked fully) * Ostrich fern, ''Matteuccia struthiopteris'', found in northern regions worldwide, and the central/eastern part of North America '' ( ...

Athyrium Filix-femina
''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 USA. It is often abundant (one of the more common ferns) in damp, shady woodland environments and is often grown for decoration. Its common names "lady fern" and "female fern" refer to how its reproductive structures ( sori) are concealed in an inconspicuous – deemed "female" – manner on the frond. Alternatively, it is said to be feminine because of its elegant and graceful appearance. Characteristics ''Athyrium filix-femina'' is now commonly split into three species, typical ''A. filix-femina'', '' A. angustum'' (narrow lady fern) and '' A. asplenioides'' (southern lady fern). ''Athyrium filix-femina'' is cespitose (the fronds arising from a central point as a clump rather than along a rhizome). The deciduous fronds are light yellow-green, long and broad. Sori appear as dots on the underside of the frond, 1� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plant Propagation
Plant propagation is the process by which new plants grow from a variety of sources: seeds, cuttings, and other plant parts. Plant propagation can also refer to the man-made or natural dispersal of seeds. Propagation typically occurs as a step in the overall cycle of plant growth. For seeds, it happens after ripening and dispersal; for vegetative parts, it happens after detachment or pruning; for asexually-reproducing plants, such as strawberry, it happens as the new plant develops from existing parts. Plant propagation can be divided into four basic types: sexual, asexual (vegetative), layering, and grafting. Countless plants are propagated each day in horticulture and agriculture. The materials commonly used for plant propagation are seeds and cuttings. Sexual propagation Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may ...

East Asia
East Asia is the eastern region of Asia, which is defined in both geographical and ethno-cultural terms. The modern states of East Asia include China, Japan, Mongolia, North Korea, South Korea, and Taiwan. China, North Korea, South Korea and Taiwan are all unrecognised by at least one other East Asian state due to severe ongoing political tensions in the region, specifically the division of Korea and the political status of Taiwan. Hong Kong and Macau, two small coastal quasi-dependent territories located in the south of China, are officially highly autonomous but are under Chinese sovereignty. Japan, Taiwan, South Korea, Mainland China, Hong Kong, and Macau are among the world's largest and most prosperous economies. East Asia borders Siberia and the Russian Far East to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To the east is the Pacific Ocean and to the southeast is Micronesia (a Pacific Ocean island group, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Fern
''Osmunda regalis'', or royal fern, is a species of deciduous fern, native to Europe, Africa and Asia, growing in woodland bogs and on the banks of streams. The species is sometimes known as flowering fern due to the appearance of its fertile fronds. Names The name ''Osmunda'' possibly derives from ''Osmunder'', a Saxon name for the god Thor. The name "royal fern" derives from its being one of the largest and most imposing European ferns. The name has been qualified as "old world royal fern" in some American literature to distinguish it from the closely related American royal fern, '' O. spectabilis''. However this terminology is not found in British literature. Description ''Osmunda regalis'' produces separate fertile and sterile fronds. The sterile fronds are spreading, tall and broad, bipinnate, with 7-9 pairs of pinnae up to long, each pinna with 7-13 pairs of pinnules 2.5-6.5 cm long and 1–2 cm broad. The fertile fronds are erect and shorter, 20–50 cm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stenochlaena
''Stenochlaena'' is a genus of ferns of the plant family Blechnaceae. Six species were formally accepted in an April 2013 scientific review of the genus, first written some years earlier and submitted in 2009. One additional species ''S. hainanensis'' awaits confirmation of its difference from ''S. palustris'' by means of differences in fertile material and/or its formal publication. One additional likely species grows naturally in Cameroon, Africa, recognised with the descriptive name ''Stenochlaena'' sp. 'Cameroon' but it awaits formal description. Some species of Stenochlaena are common as climbing ferns in South-East Asian rainforests. After the end-Cretaceous mass extinction caused by an asteroid impact, a species of Stenochlaena was essentially the only common plant across North America for several thousand years. ''Stenochlaena palustris'' is known as ''midin'' in Sarawak, Malaysia and it is eaten as a popular vegetable similar to fiddlehead ferns, which is usually flavour ...

Stenochlaena Palustris
''Stenochlaena palustris'' ( vi, choại, tl, dilimán or ''hagnaya'') is an edible medicinal fern species. In the folk medicines of India and Malaysia, the leaves of this fern are used as remedies for fever, skin diseases, ulcers, and stomachache. This plant is a long-climbing fern with thin black scales and stems that can reach up to 20 m. It has pinnate fronds that are 30–100 cm long, petioles that are 7–20 cm long, and ovate lanceolate pinnae that are 10–15 cm long and 1.5–4.5 cm wide. The fern's sporophylls are long and narrow, and have brownish sori underneath. Acylated flavonol glycosides isolated from the fern were found to have antibacterial activities. Crude and partially purified extracts prepared from the fern have been shown to exhibit antifungal, antioxidant, and antiglucosidase activities. The district of Diliman in Quezon City, one of the Philippines' most important educational districts, is named after this fern. The species epit ...
