Trichomanes Elegans
''Trichomanes elegans'' is a fern species in the family Hymenophyllaceae. The name has also been used incorrectly for two different species. Taxonomy ''Trichomanes elegans'' was first described by Louis Claude Richard in 1792. Two other species were later called ''Trichomanes elegans'': * ''Trichomanes elegans'' Poir. is an illegitimate synonym of '' Davallia denticulata'' (Burm.) Mett. * ''Trichomanes elegans'' Rudge is an illegitimate synonym of ''Trichomanes diversifrons ''Trichomanes'' is a genus of ferns in the family Hymenophyllaceae, termed bristle ferns.

Louis Claude Richard
Louis Claude Marie Richard (19 September 1754 – 6 June 1821) was a French botanist and botanical illustrator. Richard was born at Versailles. Between 1781 and 1789 he collected botanical specimens in Central America and the West Indies. On his return he became a professor at the École de médecine in Paris. His books included ''Demonstrations botaniques'' (1808), ''De Orchideis europaeis'' (1817), ''Commentatio botanica de Conifereis et Cycadeis'' (1826) and ''De Musaceis commentatio botanica'' (1831). He gave us the special description terminology for the orchids, such as pollinium and gynostemium. The genus ''Richardia'' Kunth, (Araceae) was named in his honor. It is now a synonym of the genus ''Zantedeschia'' . This botanist is denoted by the author abbreviation when citing a botanical name. His son was another notable botanist, Achille Richard. He also discovered Morgat in the 1880s. Eponyms A species of Caribbean lizard, ''Anolis richardii'', is named in honor of ...

Hymenophyllaceae
The Hymenophyllaceae, the filmy ferns and bristle ferns, are a family of two to nine genera (depending on classification system) and about 650 known species of ferns, with a subcosmopolitan distribution, but generally restricted to very damp places or to locations where they are wetted by spray from waterfalls or springs. A recent fossil find shows that ferns of Hymenophyllaceae have existed since at least the Upper Triassic. Description They often appear as very dark green or even black clumps and may be mistaken for a robust moss or liverwort. The rhizome is usually thin and wiry and the fronds variously pinnate with a single strand ("nerve") of vascular tissue. As in most ferns, young fronds have circinate vernation. In most species, the frond, apart from the vascular tissue, is only a single cell thick, and they do not have any stomata. The cuticle is also greatly reduced or absent, leaving filmy ferns very susceptible to desiccation where a reliable water supply is not ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

Davallia Denticulata
''Davallia denticulata'' is a widespread species of fern. Often seen as a lithophyte or epiphyte in different forest types. It may lose all its fronds in dry periods.

Trichomanes Diversifrons
''Trichomanes'' is a genus of ferns in the family Hymenophyllaceae, termed bristle ferns. The circumscription of the genus is disputed. All ferns in the genus are filmy ferns, with leaf tissue typically 2 cells thick. This thinness generally necessitates a permanently humid habitat, and makes the fronds somewhat translucent. Because of this membrane-like frond tissue, the plant is prone to drying out. “Filmy ferns” in the taxa Hymenophyllaceae grow in constantly wet environments. Many are found in cloud forests such as “Choco” in Colombia. There are also members of the taxa that can grow submersed in water. The name bristle fern refers to the small bristle that protrudes from the indusia of these ferns. Taxonomy The genus ''Trichomanes'' was first described by Carl Linnaeus in 1753. Its status, like other genera in the subfamily Trichomanoideae, remains disputed. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts the genus as one of eight in the sub ...
