Kaulinia

Kaulinia is a genus of Polypodiaceae, a family of ferns. , it is regarded as a synonym of "Microsorum". 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. The genus might be recognized in the future.
