Tricholepidium Venosum
''Tricholepidium'' is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Taxonomy ''Tricholepidium'' was first described by Ren-Chang Ching in 1978. A molecular phylogenetic study in 2019 suggested that ''Tricholepidium'' was one of a group of closely related genera in the subfamily Microsoroideae, a group the authors termed "''Lepisorus'' sensu lato". Its species were embedded in a clade in which none of the genera appeared to be monophyletic: Species The Pteridophyte Phylogeny Group classification of 2016 (PPG I) separates the monotypic genus ''Lepidomicrosorium'' from ''Tricholepidium''. , neither the ''Checklist of Ferns and Lycophytes of the World'' nor ''Plants of the World Online'' accepted the separation, and so placed ''Lepidomicrosorium subhastatum'' in ''Tricholepidium'' (as ''Tricholepidium buergerianum'') along with four other species: *''Tricholepidium norma ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images.

Paragramma (plant)
''Paragramma'' is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). There is a single species, ''Paragramma longifolia''. Other sources do not accept the genus, submerging it into ''Lepisorus'', with ''Paragramma longifolia'' becoming ''Lepisorus longifolius'' (Blume) Holttum. A molecular phylogenetic study in 2019 showed that ''Lepisorus longifolius'' was sister to all the remaining species of ''Lepisorus'', which formed a clade A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree.

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate ( Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid fe ...
