Matteuccia
''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'', bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Onocleaceae
Onocleaceae is a small family of terrestrial ferns in the order Polypodiales. It is placed in the suborder Aspleniineae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the family, along with Blechnaceae, may be placed in a very broadly defined family Aspleniaceae as the subfamily Blechnoideae. The family may contain from one to four genera, consisting of five species largely in north temperate climes. The four genera, '' Matteuccia'', '' Onoclea'', '' Onocleopsis'' and ''Pentarhizidium'', may be included under the single genus ''Onoclea''. Description Members of the family have the following characteristics, being distinguished by having strongly dimorphic fronds, with the fertile fronds different from the sterile fronds. The rhizomes are long- to short-creeping to ascending, and sometimes stoloniferous (''Matteuccia'' and ''Onocleopsis''). The leaves are strongly dimorphic and the petioles have two vascular bundles uniting distally into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiddlehead Sprouts As Food In Tokyo Area March 9 2020
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 '' ...

Ferns Of The United States
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 f ...

Onoclea
''Onoclea'' is a genus of plants in the family Onocleaceae, native to moist habitats in eastern Asia and eastern North America. They are deciduous ferns with sterile fronds arising from creeping rhizomes in spring, dying down at first frost. Fertile fronds appear in late summer. Depending on the authority, the genus contains one to five species.

Sthenopis Pretiosus
''Sthenopis pretiosus'', the gold-spotted ghost moth, is a species of moth of the family Hepialidae. It was first described by Gottlieb August Wilhelm Herrich-Schäffer in 1856. It can be found in found Brazil, Venezuela and in the eastern United States and south-eastern Canada. Naming history ''Sthenopis pretiosus'' was independently discovered, named and described at least three times: #It was first found in Brasil and described by Gottlieb August Wilhelm Herrich-Schäffer in 1856 who called it ''Epialus pretiosus''. The type specimen of ''E. pretiosus'' has not been located. #It was also found in the north-eastern United States and south-eastern Canada and described by Augustus Radcliffe Grote in 1878, who called it ''Hepialus auratus'' which become ''Sthenopis auratus''. #It was also found in Venezuela and described by Rudolf Pfitzner in 1906, who called it ''Phassus eldorado''. Later Pfitzner published an illustration of ''Phassus eldorado''. The holotype of ''P. eldorado'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
