The nomenclature of the Catostemma clade (Malvaceae/Bombacoideae/Adansonieae)

Aguiaria , Catostemma , and Scleronema (Malvaceae) are restricted to Amazonia, and comprise 20 accepted (and one uncertain) species that are typically large trees with significant economic value. No recent studies or taxonomic reviews of these three genera exist, and our preliminary evaluation indicated that many names need to be lectotypified. We present here a detailed review of all the names related to these three genera, with comments, corrected names, lectotypification of 10 names, and epitypification for three names. This article provides a basis for future systematic and evolutionary studies of both the Catostemma clade and of the tribe Adansonieae, in which that clade is embedded.
