Fiddlehead
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 '' (See heal ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.

Ostrich Fern
''Matteuccia'' is a genus of ferns with one species: ''Matteuccia struthiopteris'' (common names ostrich fern, fiddlehead fern, or shuttlecock fern). The species epithet ''struthiopteris'' comes from Ancient Greek words () "ostrich" and () "fern". Description The fronds are dimorphic, with the deciduous green sterile fronds being almost vertical, tall and broad, long-tapering to the base but short-tapering to the tip, so that they resemble ostrich plumes, hence the name. The fertile fronds are shorter, long, brown when ripe, with highly modified and constricted leaf tissue curled over the sporangia; they develop in autumn, persist erect over the winter and release the spores in early spring. Along with ''Dryopteris goldieana'', it is one of the largest species of fern in eastern North America. Classification ''Matteuccia struthiopteris'' is the only species in the genus ''Matteuccia''. Some sources include two Asian species, ''M. orientalis'' and ''M. intermedia'', but molec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bracken
Bracken (''Pteridium'') is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm). Brackens are noted for their large, highly divided leaves. They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland. The genus probably has the widest distribution of any fern in the world. The word ''bracken'' is of Old Norse origin, related to Swedish ''bräken'' and Danish ''bregne'', both meaning fern. In the past, the genus was commonly treated as having only one species, ''Pteridium aquilinum'', but the recent trend is to subdivide it into about ten species. Like other ferns, brackens do not have seeds or fruits, but the immature fronds, known as ''fiddleheads'', are sometimes eaten, although some are thought to be carcinogenic. Description an ...

Frond
A frond is a large, divided leaf. In both common usage and botanical nomenclature, the leaves of ferns are referred to as fronds and some botanists restrict the term to this group. Other botanists allow the term frond to also apply to the large leaves of cycads, as well as palms (Arecaceae) and various other flowering plants, such as mimosa or sumac. "Frond" is commonly used to identify a large, compound leaf, but if the term is used botanically to refer to the leaves of ferns and algae it may be applied to smaller and undivided leaves. Fronds have particular terms describing their components. Like all leaves, fronds usually have a stalk connecting them to the main stem. In botany, this leaf stalk is generally called a petiole, but in regard to fronds specifically it is called a stipe, and it supports a flattened blade (which may be called a lamina), and the continuation of the stipe into this portion is called the rachis. The blades may be simple (undivided), pinnatifid ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
