Abstract

SummaryPichi Sermolli (1972) has cited Mertensia dichotoma (Thunb. ex Murray) Willd. as lectotype of Mertensia Willd. In so doing he has ignored the taxonomic facts on which earlier citation of M. truncata Willd. as type of Mertensia considered as a subgeneric name was based. The facts are briefly re‐stated, and the selection of M. truncata as type of the genus defended. Brief notes are added on the genera Sticherus and Hicriopteris of Presl. A general objection is made to nomenclatural decisions made without reference to taxonomic considerations.
