Tricholepidium
''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 The Pteridophyte Phylogeny Group, or PPG, is an informal international group of systematic botanists who collaborate to establish a consensus on the classification of pteridophytes ( lycophytes and ferns) that reflects knowledge about plant relatio ... classification of 2016 (PPG I) separates the monotypic genus '' Lepidomicrosorium'' from ''Tricholepidium''. , neither the ''Checklist of ...

Microsoroideae
Microsoroideae is a subfamily in the fern family Polypodiaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The subfamily is also treated as the tribe Microsoreae within a very broadly defined family Polypodiaceae ''sensu lato''. In either treatment, it includes the previously separated tribe Lepisoreae. Taxonomy The taxonomy of the subfamily Microsoroideae has been described as "highly problematic". The division into genera varies considerably. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognized the following genera, while accepting that some needed further evaluation: :*'' Goniophlebium'' (Blume) C.Presl :*''Lecanopteris'' Reinw. ex Blume :*'' Lemmaphyllum'' C.Presl :*'' Lepidomicrosorium'' Ching & K.H.Shing :*'' Lepisorus'' (J.Sm.)

Polypodiaceae
Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae. A broader circumscription has also been used, in which the family includes other families kept separate in PPG I. Nearly all species are epiphytes, but some are terrestrial. Description Stems of Polypodiaceae range from erect to long-creeping. The fronds are entire, pinnatifid, or variously forked or pinnate. The petioles lack stipules. The scaly rhizomes are generally creeping in nature. Polypodiaceae species are found in wet climates, most commonly in rain forests. In temperate zones, most species tend to be epiphytic or epipetric. Notable examples of ferns in this family include the resurrection fern (''Pleopeltis polypodioides'') and the golden serpent fern (''Phlebodium aureum''). Taxonomy Two distinct circumscriptions of the family are in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.
