Lectotypes of Abeliophyllum distichum (Oleaceae) and its Two Forms

Abstract

Abeliophyllum distichum Nakai, a Korean endemic species belonging to a monotypic genus of Oleaceae, was described by Nakai in 1919 based on four specimens cited in the protologue. He added two forms of the species in 1922, f. albiflorum Nakai and f. lilacinum Nakai, without citation of the specimens he actually examined. After examining the syntypes of A. distichum [f. disticum] and the original material of f. albiflorum Nakai and f. lilacinum Nakai, we selected, and designate here, the lectotypes of these taxa.
