Asplenium × Virginicum
''Asplenium'' is a genus of about 700 species of ferns, often treated as the only genus in the family Aspleniaceae, though other authors consider '' Hymenasplenium'' separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is '' Asplenium marinum''. The most common vernacular name is spleenworts, applied to the more "typical" species. '' A. nidus'' and several similar species are called bird's-nest ferns, the ''Camptosorus'' group is known as walking ferns, and distinct names are applied to some other particularly well-known species. Etymology From New Latin ''asplenium'' (“spleenworts”), Linnaeus's adjustment of Latin ''asplenon'' (“spleenwort”), from Ancient Greek ἄσπληνον (''ásplēnon'', “spleenwort”), from ἀ- (''a-'', “un-”) + σπλήν (''splḗn'', “spleen”) + -ον (''-on'', “-um”), from its use to cure anthrax in liv ...

Asplenium Trichomanes
''Asplenium trichomanes'', the maidenhair spleenwort (not to be confused with the similar-looking Adiantum, maidenhair fern), is a small fern in the spleenwort genus ''Asplenium''. It is a widespread and common species, occurring almost worldwide in a variety of rocky habitats. It is a variable fern with several subspecies. The binomial nomenclature, specific epithet ''trichomanes'' refers to a Greek word for fern. Description ''Asplenium trichomanes'' is a small plant forming tufts between tall, arising from a short, scaly rhizome. The scales are dark and the evergreen fronds are long and narrow, gradually tapering towards the tip. They are simply divided into small, yellow-green to dark-green, roundish leaflets or pinnae. The stipe (botany), stipe and rachis of the frond are dark all along their length. The fronds can reach in length but are more commonly between . The Sorus, indusia are linear to oval, straight, and attached to the upper-side of the fertile vein. There are u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
