Dryopteris Clintoniana
''Dryopteris clintoniana'', commonly known as Clinton's wood fern, is a fern of hybrid origin native to the northern hemisphere. It is a fertile hexaploid, arising as a species by doubling of its chromosome number from a hybrid between ''Dryopteris cristata'', a tetraploid, and ''Dryopteris goldieana ''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. It is the largest native North American speci ...'', a diploid. It is more northern in its range than either parent species. This fern will be found in wet areas, similar to the habitat of ''D. cristata''.

Philip Dowell
Philip, also Phillip, is a male given name, derived from the Greek (''Philippos'', lit. "horse-loving" or "fond of horses"), from a compound of (''philos'', "dear", "loved", "loving") and (''hippos'', "horse"). Prominent Philips who popularized the name include kings of Macedonia and one of the apostles of early Christianity. ''Philip'' has many alternative spellings. One derivation often used as a surname is Phillips. It was also found during ancient Greek times with two Ps as Philippides and Philippos. It has many diminutive (or even hypocoristic) forms including Phil, Philly, Lip, Pip, Pep or Peps. There are also feminine forms such as Philippine and Philippa.

Dryopteris Cristata
''Dryopteris cristata'' is a species of fern native to wetlands throughout the Northern Hemisphere. It is known as crested wood fern or crested buckler-fern. This plant is a tetraploid species of hybrid origin, one parent being ''Dryopteris ludoviciana'' and the other being the unknown, apparently extinct species, dubbed ''Dryopteris semicristata'', which is also one of the presumed parents of ''Dryopteris carthusiana''. ''D. cristata'' in turn is one of the parents of ''Dryopteris clintoniana'', another fern of hybrid origin. The crested wood fern is a wetlands plant, needing year-round moisture. The fronds often grow quite tall, up to a meter or more in height, but are extremely narrow under most conditions. Anti-microbial properties It is known that this plant has been used as an anti-microbial agent; for example, root extracts from ''D. cristata'' (as well as the kindred species ''Dryopteris arguta, D. arguta'') has been shown efficacious in expelling intestinal parasites fr ...

Dryopteris Goldieana
''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. 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. Specimens are known with fronds six feet (1.8 meters) tall. ''D. goldieana'' hybridizes with many other species of ''Dryopteris'' and the hybrids tend to be larger than the pure species. It was named by William Hooker in honor of its discoverer, John Goldie. The epithet was originally published as ''goldiana'', but this is regarded as a misspelling to be corrected. Description Goldie's fern is common in moist rich woods, ravines, seeps, or at the edges of swamps and in areas with full or partial shade. It grows in a clumped form where all the leave emerge from the same point on the ground. The stipe, the division of stem which emerg ...

Dryopteris
:''The moth genus ''Dryopteris'' is now considered a junior synonym of '' Oreta. ''Dryopteris'' , commonly called the wood ferns, male ferns (referring in particular to ''Dryopteris filix-mas''), or buckler ferns, is a fern genus in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). There are about 300-400 species in the genus. The species are distributed in Asia, the Americas, Europe, Africa, and the Pacific islands, with the highest diversity in eastern Asia. It is placed in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Many of the species have stout, slowly creeping rootstocks that form a crown, with a vase-like ring of fronds. The sori are round, with a peltate indusium. The stipes have prominent scales. Hybridization and polyploidy are well-known phenomena in this group, with many species forme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1867
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Flora Of North America
The ''Flora of North America North of Mexico'' (usually referred to as ''FNA'') is a multivolume work describing the native plants and naturalized plants of North America, including the United States, Canada, St. Pierre and Miquelon, and Greenland. It includes bryophytes and vascular plants. All taxa are described and included in dichotomous keys, distributions of all species and infraspecific taxa are mapped, and about 20% of species are illustrated with line drawings prepared specifically for FNA. It is expected to fill 30 volumes when completed and will be the first work to treat all of the known flora north of Mexico; in 2015 it was expected tha the series would conclude in 2017. Twenty-nine of the volumes have been published as of 2022. Soon after publication, the contents are made available online. FNA is a collaboration of about 1,000 authors, artists, reviewers, and editors from throughout the world. Reception The series has been praised for "the comprehensive treatme ...

Flora Of Asia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
