Microsorum

Microsorum is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[3] 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).[3] As of February 2019, both the Checklist of Ferns and Lycophytes of the World and Plants of the World Online kept Phymatosorus separate.[4][5] 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:[6]

gollark: ?¿
gollark: Sure, I guess.
gollark: No, but it's nice to be able to refer to "Protagonism Street" and have there be no ambiguity.
gollark: ./warp choruscity
gollark: Which we probably do have right now, actually. There are something like... three cities. Cherryville is tiny, Chorus City uses weird names picked by me, and Switch City, well, has roads.
