A New Tribal Classification of Grewioideae (Malvaceae) Based on Morphological and Molecular Phylogenetic Evidence

Abstract

— A systematic re-evaluation of Grewioideae (Malvaceae) is provided. The results are based on analysis of morphological and DNA sequence data (ndhF). Investigations on floral morphology, anatomy, ontogeny, as well as on fruit and leaf morphology, and DNA data of Grewioideae and related genera contribute significantly to a better understanding of the intricate phylogenetic relationships of this plant group. The study documents that former classifications of Grewioideae need to be amended in favor of a new subdivision into two tribes, Apeibeae and Grewieae.
