Taxonomy

The genus Japanobotrychum was first described in 1931 by the Japanese botanist Genkei Masamune, with the only species being Japanobotrychum arisanense.[3] This is now considered to be a synonym of Botrychium lanuginosum Wall. ex Hook. & Grev., first described in 1828,[1] so the epithet lanuginosum has priority over arisanense. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts the genus (with the spelling "Japanobotrychium"), with one species,[2] as did the Checklist of Ferns and Lycophytes of the World as of October 2019,[1] whereas Plants of the World Online subsumed the genus into Botrychium.[4]

Distribution

Japanobotrychum lanuginosum is widely distributed, mainly in tropical Asia, being found from West Himalaya and India through southern China and Mainland Southeast Asia to New Guinea.[5]
