Lectotypification of Six Fern Taxa Described by Tomitaro Makino Based on Specimen Investigation at MAK, TI and TNS Herbaria

Abstract

Lectotypes are designated for six taxa among the 90 new ferns and lycophyte taxa described by Tomitaro Makino, considered to be particularly high priority for nomenclatural stability. Prior to lectotypification, a thorough database and on-site investigation of specimens was conducted at the three herbaria (MAK, TI and TNS) that house important specimens collected by Makino, and the found specimens were carefully compared with their respective protologues to determine their status. We also explored the type specimens of Cyrtomium fortunei var. clivicola but were unable to find any specimen with pinnae sizes matching the protologue.
