Microsorum
Sign in to saveMicrosorum 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.

Kaulinia is a genus of Polypodiaceae, a family of ferns. As of August 2019, it is regarded as a synonym of Microsorum.[1][2] It was named after Kailas Nath Kaul, an Indian botanist and agricultural scientist. In a morphological study of the sporophytes and gametophytes of several species of Microsorum, it became apparent that at least two phyletically distinct groups of species existed in the genus. The group represented by Microsorum pteropus and Microsorum hancockii seemed to have a different ancestry from the other group, and were placed in a genus known as Kaulinia. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts that Microsorum is not monophyletic, but states that further study is needed.[1] The genus might be recognized in the future.

==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:
