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] |

Microsorum
''Microsorum'' is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The species are tropical. Like most ferns, they grow from rhizomes, rather than roots. The genus name is often misspelled "Microsorium" or "Microsoreum". It includes some species that are lithophytic rheophytes. Taxonomy The genus ''Phymatosorus'' is included in ''Microsorum'' in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). , both the ''Checklist of Ferns and Lycophytes of the World'' and ''Plants of the World Online'' kept ''Phymatosorus'' separate. A 2019 molecular phylogenetic study of the subfamily Microsoroideae did not distinguish ''Phymatosorus'' from ''Microsorum'', and suggested that the genus as there circumscribed was sister to '' Leptochilus'', together forming one of the three main clades in the subfamily: Species , the ''Checklist of Ferns and Lycophytes of the World'' ...

Lepisorus Thunbergianus
''Lepisorus'' is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Taxonomy ''Lepisorus'' was first described by John Smith in 1846 as the section ''Lepisorus'' of the genus ''Drynaria''. It was raised from a section to a genus by Ren-Chang Ching in 1933. A molecular phylogenetic study in 2019 suggested that ''Lepisorus'' was one of a group of closely related genera in the subfamily Microsoroideae, a group the authors termed "''Lepisorus'' sensu lato".

Zealandia (plant)
''Zealandia'' is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, erected in 2019. , the genus was not accepted by some sources. Taxonomy The division of the subfamily Microsoroideae into genera has long been uncertain. A 2019 molecular phylogenetic study suggested that there were three clades close to ''Lecanopteris'' sensu stricto and distinct from other clades in the subfamily. The authors of the study preferred to set up three extra monophyletic genera, rather than use a broader circumscription of ''Lecanopteris''. The genera are related as shown in the following cladogram. , the ''Checklist of Ferns and Lycophytes of the World'' recognized the segregate genera, including ''Zealandia''; other sources did not.

Dendroconche
''Dendroconche'' is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, erected in 2019. , the genus was not accepted by some sources. Description Species of ''Dendroconche'' are usually partially epiphytic. They grow from long, creeping rhizomes that are flattened from top to bottom and bear brown scales. In some species, the rhizome may have cavities. The rhizome produces two kinds of roots: those from the sides grip the surface on which the plant grows; those from underneath enter the substrate. The leaves vary in shape from undivided to deeply divided, and are up to 70 cm long by 40 cm wide. Some species produce leaves of somewhat different shapes. The leaves may or may not have a petiole, which if present is usually winged. The leaf veins are prominent. The sori are round or elongated. Taxonomy The division of the subfamily Microsoroideae into genera has long been uncertain. A 2019 molecular phylogenetic study suggested that there were thre ...

Bosmania
''Bosmania'' is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, erected in 2019. , the genus was not accepted by some sources. Description ''Bosmania'' species are terrestrial plants, lithophytes or epiphytes. They grow from creeping rhizomes that are circular in cross-section, or slightly flattened from top to bottom, with roots emerging from the underside. The rhizome has brown scales, 1.5–9 mm long, 1–3 mm wide. Their leaves are elliptical in shape, undivided, up to 110 cm long and 15 cm wide, and have a wingless petiole 1–15 cm long. A characteristic of the genus is that the leaves are "seasonally deciduous", i.e. shed during unfavourable conditions. The blade of the leaf (lamina) is thin with prominent veins. The sori are round to slightly elliptical with bright yellow monolete spores. Taxonomy The division of the subfamily Microsoroideae into genera has long been uncertain.
