A First Phylogeny of the Genus Dimocarpus and Suggestions for Revision of Some Taxa Based on Molecular and Morphological Evidence

Abstract Dimocarpus longan, commonly known as the longan, belongs to the family Sapindaceae, and is one of the most economically important fruits commonly cultivated in several regions in Asia. There are various cultivars of longan throughout the Thai-Malay peninsula region, but until now no phyloge...
