Integration of leaf traits supports the current circumscription of Afgekia Craib. and Padbruggea Miq. (Fabaceae, Wisterieae)
Accurate delimitation of Afgekia and Padbruggea, two morphologically similar genera in the tribe Wisterieae (Fabaceae), has long posed challenges by overlapping vegetative traits, particularly in the case of P. filipes, which had been historically misclassified under Afgekia. This study aims to…
