Convergent morphology in alpinieae (Zingiberaceae): Recircumscribing amomum as a monophyletic genus

The tropical ginger genus Amomum (Zingiberaceae) has always posed challenges for classification based on morphological characters. Previous molecular phylogenetic studies showed Amomum to be paraphyletic but limited sampling and absence of the data of the type Amomum subulatum made it impossible to...
