Adiantum
''Adiantum'' (), the maidenhair 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 high diversity also occurs in eastern Asia, with nearly 40 species in China. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Sorus, sori (masses of spores) form beneath a curled-under leaflet edge (indusium, false indusium).

Adiantum Pedatum
''Adiantum pedatum'', the northern maidenhair fern or five-fingered 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'' in 1753 (the official starting point of modern botanical nomenclature). He referred to earlier descriptions, all based on material from eastern North America. Linnaeus' own herbarium contains one specimen, collected by Pehr Kalm. Specimens collected in Unalaska and Kodiak Island by Chamisso and Langsdorf were referred to as ''Adiantum boreale'' by Presl in 1836, although he did not provide a species description to accompany the name. Ruprecht, in 1845, called the Alaskan material ''A. pedatum'' var. ''aleuticum'', and created var. ''kamtschaticum'' for mater ...

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. ''Adiantum aethiopicum'' was one of the many species first described by Linnaeus, in this case in his ''Systema naturae'' in 1759. The specific epithet ''aethiopicum'' in this sense was the Latin term for Africa south of the then known world, that is to say, more or less Africa south of Egypt. In South Africa the species occurs widely, though not generally profusely, mainly on moist sandstone cliffs in full shade.

Adiantum × Mairisii
''Adiantum'' × ''mairisii'' (/adiˌantəm bʌɪ mɛːɪsɪˌʌɪ/) (also known as Mairis maidenhair fern) is a species of fern in the family Pteridaceae. Taxonomy This species is a sterile hybrid between the southern maidenhair (''Adiantum capillus-veneris'') and another unknown species. The species is hypothesised to be: * ''Adiantum raddianum'' * ''Adiantum aethiopicum'' * ''Adiantum cuneatum'' This species is more frost-resistant than either of its parents. Discovery Thomas Moore, who collected ferns during the Victorian period named the hybrid in the second half of the 19th century. It was described in his book, titled: "''Nature-Printed British Ferns''". Cultivation This species has gained the Royal Horticultural Society's Award of Garden Merit. The reason why this fern species is popular is due to its winter-hardiness relative to other species in the genus. The UK hardiness rating is H5, while the USDA The United States Department of Agriculture (USDA) is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adiantum Jordanii
''Adiantum jordanii'' is a perennial species of Adiantum, 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 sorus, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
