Matteuccia is a genus of ferns with one species: Matteuccia struthiopteris (common names ostrich fern, fiddlehead fern, or shuttlecock fern). [4] The species epithet struthiopteris comes from Ancient Greek words στρουθίων ( strouthíōn ) "ostrich" and πτερίς ( pterís ) "fern".
Four genera, with a total of five species, are accepted. [2] [8] Matteuccia. Matteuccia struthiopteris (ostrich fern) - wide distribution including North America, Europe, and Asia; Onoclea. Onoclea sensibilis (sensitive fern) - North America and eastern Asia, with the American and Asian populations being recognized as distinct varieties ...
Pentarhizidium orientale, the Oriental ostrich fern, is a fern native to China, Japan, and the Himalayas. It grows to about 0.6 m (2 ft) in height by 0.6 m (2 ft) wide. It was formerly included in the genus Matteuccia, but phylogenetic studies mandated that it and Pentarhizidium intermedium be moved to a new genus.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
Not all species contain ptaquiloside, such as Diplazium esculentum, a fern with fiddleheads regularly consumed in parts of East Asia, which differs from bracken (Pteridium aquilinum). [ 4 ] The fiddlehead resembles the curled ornamentation (called a scroll ) on the end of a stringed instrument, such as a fiddle .
The largest species, the lined butterflyfish and the saddle butterflyfish, C. ephippium, grow to 30 cm (12 in). The common name references the brightly coloured and strikingly patterned bodies of many species, bearing shades of black, white, blue, red, orange, and yellow. Other species are dull in colour.
Dryopteris goldieana, commonly called Goldie's wood fern, or giant wood fern is a fern native to the eastern United States and adjacent areas of Canada, from New Brunswick to Ontario and Georgia. [3] It is the largest native North American species of Dryopteris and along with ostrich fern it is one of the largest ferns in eastern North America.
Aspleniineae is a suborder of ferns in the order Polypodiales. It is equivalent to the clade eupolypods II in earlier systems; [1] [2] it is also treated as a single very broadly defined family Aspleniaceae. [3] The suborder generally corresponds with the order Blechnales as described by J. L. Reveal in 1993. [4]
