Nomenclatural changes in Zingiberaceae: Haplochorema is reduced to Boesenbergia

Abstract

The history of Haplochorema K.Schum. (Zingiberaceae) is reviewed, its morphology is compared to Boesenbergia Kuntze and the molecular phylogenetic position is shown in relation to other Zingiberaceae. Based on a comparative analysis of molecular and morphological data, Haplochorema is reduced to Boesenbergia with eight new combinations. A lectotype for Boesenbergia loerzingii (Valeton) K.Larsen ex M.F.Newman, Lhuillier & A.D.Poulsen is designated here.
