Adiantum
''Adiantum'' (), the maidenhair fern (not to be confused with the similar-looking maidenhair spleenwort fern), is a genus of about 250 species of ferns in the subfamily Vittarioideae of the family Pteridaceae, though some researchers place it in its own family, Adiantaceae. The genus name comes from Greek, meaning "unwetted", referring to the fronds' ability to shed water without becoming wet. Description They are distinctive in appearance, with dark, often black stipes and rachises, and bright green, often delicately cut leaf tissue. The sori are borne submarginally, and are covered by reflexed flaps of leaf tissue which resemble indusia. Dimorphism between sterile and fertile fronds is generally subtle. They generally prefer humus-rich, moist, well-drained sites, ranging from bottomland soils to vertical rock walls. Many species are especially known for growing on rock walls around waterfalls and water seepage areas. The highest species diversity is in the Andes. Fairly ...

Adiantum Aleuticum
''Adiantum aleuticum'', the western maidenhair fern or Aleutian maidenhair, is a species of deciduous fern in the genus '' Adiantum''. Description ''A. aleuticum'' typically grows about 18-30 inches tall and wide. The fronds grow tall, and are fan-shaped, light to medium green with dark brown to black stems. When growing in relative shade, fronds are held horizontally, but it also can grow in high mountains in full sun (often on serpentine rock) with fronds held vertically. New fronds unfurl from a tight coil ( circinate vernation) held on a tall stalk. Oblong sori (masses of spores) form beneath a curled-under leaflet edge ( false indusium).

Adiantum Pedatum
''Adiantum pedatum'', the northern maidenhair fern, is a species of fern in the family Pteridaceae, native to moist forests in eastern North America. Like other ferns in the genus, the name maidenhair refers to the slender, shining black stipes. Description ''A. pedatum'' grows tall, and is deciduous. Taxonomy ''Adiantum pedatum'' was described by Linnaeus in ''Species Plantarum ' (Latin for "The Species of Plants") is a book by Carl Linnaeus, originally published in 1753, which lists every species of plant known at the time, classified into genus, genera. It is the first work to consistently apply binomial nomenclature ...'' in 1753 (the official starting point of modern botanical nomenclature).

Adiantum Aethiopicum
''Adiantum aethiopicum'', also known as the common maidenhair fern, is a small fern of widespread distribution, occurring in Africa, Australia, Norfolk Island and New Zealand.

The specific epithet ''aethiopicum'' in this sense was the Latin Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages.

Adiantum Jordanii
''Adiantum jordanii'' is a perennial species of maidenhair fern, in the Vittarioideae subfamily of the Pteridaceae. The species is known by the common name California maidenhair. It is native to California and Baja California. ''A. jordanii'' is found in the southernmost part of its range in Baja California with such flora associates as '' Mimulus aridus'' and '' Daucus pusillus''. Each trailing leaf may reach over half a meter in length and is made up of many rounded green segments. Each segment has two to four lobes and it may split between the lobes, the underside of each segment bearing one to four sori. ''Adiantum jordanii'' is a carrier of the fungus-like oomycete, '' Phytophthora ramorum'', which causes Sudden Oak Death. The USDA enforces an import control, focusing intensely on areas (CA, OR, NY in U.S.) that are infected with Sudden Oak death. When sold, they must be identified by place of origin and must also be accompanied by a phytosanitary certificate. The U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 s ...
