Vittarioideae
Vittarioideae is a subfamily of the fern family Pteridaceae, in the order Polypodiales. The subfamily includes the previous families Adiantaceae (adiantoids or maidenhair ferns) and Vittariaceae (vittarioids or shoestring ferns). Description The subfamily includes two distinct groups of ferns: the adiantoids, consisting of the single genus ''Adiantum'', and the vittarioids, several genera, including ''Vittaria'', which typically have highly reduced leaves, usually entire, and an epiphytic habit. The ferns historically considered as ''Adiantum'' include both petrophilic and terrestrial plants. The vittarioid ferns are primarily epiphytic in tropical regions and all have simple leaves with sori that follow the veins and lack true indusia; the sori are most often marginal with a false indusium formed from the reflexed leaf margin. The family also includes a species, '' Vittaria appalachiana'', that is highly unusual in that the sporophyte stage of the life cycle is absent. This spe ...

Vittaria Appalachiana
''Vittaria appalachiana'', or the Appalachian shoestring fern, is a fern species in the subfamily Vittarioideae of the family Pteridaceae. It is native to moist and shaded outcrops in the Appalachian Mountains. It is notable for existing only in the gametophyte stage of development, unlike other fern species in which the sporophyte stage predominates. The species reproduces asexually through gemmae. The species was known to bryologists, who at first confused it with a liverwort. Aaron John Sharp brought the species to the attention of pteridologists Warren H. Wagner and Alma Gracey Stokey. It was formally named by Farrar & Mickel in 1991. Description The sporophyte (normally the dominant generation of the fern life cycle) is almost never formed in this species. Tiny sporophytes have been found at one site in Ohio, and have twice been produced in culture. The few ''V. appalachiana'' sporophytes known have had rhizomes with clathrate (lattice-patterned) scales, and und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vittaria Lineata
''Vittaria lineata'', also known by its common name shoestring fern is a species of fern from the genus ''Vittaria''. It grows epiphytically An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phoroph ... in wet, new-world tropics and subtropics as far north as Florida.

Haplopteris
''Haplopteris'' is a genus of vittarioid ferns, a member of subfamily Vittarioideae and family Pteridaceae. Description Like other vittarioids, the members of ''Haplopteris'' are epiphytes. The rhizome has a distinct upper and lower side, lacking radial symmetry, a characteristic that separates it from '' Radiovittaria''. Leaves are borne in two ranks in a single plane, and are usually simple, occasionally forked. The leaves have a distinct costa (midrib). Most species have netlike leaf veins which form two rows of areolae (the "gaps" in the net) on either side of the midline; two species bear a single leaf vein only. The linear sori, in most species, are confined to a commissural vein (paralleling the edge of the leaf margin and set just back from it, joining the ends of the netted veins); in the two species with a single vein, the sori follow that vein. The sori bear paraphyses (minute hairs) with a cell at the tip shaped like an inverted cone, separating it from ''Vittaria'' ...

Pteridaceae
Pteridaceae is a family of ferns in the order Polypodiales, including some 1150 known species in ca 45 genera (depending on taxonomic opinions), divided over five subfamilies. The family includes four groups of genera that are sometimes recognized as separate families: the adiantoid, cheilanthoid, pteridoid, and hemionitidoid ferns. Relationships among these groups remain unclear, and although some recent genetic analyses of the Pteridales suggest that neither the family Pteridaceae nor the major groups within it are all monophyletic, as yet these analyses are insufficiently comprehensive and robust to provide good support for a revision of the order at the family level. Description Members of Pteridaceae have creeping or erect rhizomes. The leaves are almost always compound and have linear sori that are typically on the margins of the leaves and lack a true indusium, typically being protected by a false indusium formed from the reflexed margin of the leaf.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
