Flora of Singapore precursors, 19: Nomenclatural notes on Artabotrys (Annonaceae) and Magnolia (Magnoliaceae)

Abstract

During the preparation of the accounts of Artabotrys (Annonaceae) and Magnolia (Magnoliaceae) for the Flora of Singapore, the types of all relevant names were evaluated. New lectotypes are designated for A. suaveolens and M. maingayi and a second-step lectotypification is performed for M. elegans. The citation of a lectotype locality is corrected for A. costatus and the citation of an isolectotype is improved for A. maingayi. We also clarify the previous use of the term ‘type’ to designate specimens that are in fact lectotypes for several names in Magnolia.
