Type Specimens and Lectotypification of Nakaian Taxa from Ulleung Island, Korea

Abstract

Type specimens (deposited at TI) for 55 Nakaian taxa described from Ulleung Island were examined. Four taxa of those were confirmed as simple name combinations. Excluding 15 taxa which have already been lectotypified, lectotypes for 25 taxa including Arabis takesimense Nakai, Fagus multineruis Nakai, and Salix ishidoyana Nakai were designated in here. Validity of publication for the names of five taxa was not confirmed here. Type specimens for the remaining six taxa need further examination.
