Revisiting the taxonomy of Dioclea and related genera (Leguminosae, Papilionoideae), with new generic circumscriptions.

ABSTRACT: The Dioclea clade comprises four genera and aproximately 60 species of the tribe Diocleae: Cleobulia (4 species), Cymbosema (1), Dioclea (ca. 50), Luzonia (1) and Macropsychanthus (3-4). Dioclea has been demonstrated to be a non-monophyletic genus, but low sampling in previous phylogenetic studies hampered the adoption of new taxonomic arrangements. We carried out densely sampled phylogenetic analyses of the Dioclea clade using molecular markers that had performed well in previous studies: the ITS and ETS nuclear ribosomal regions and the plastid trnK/matK. Our results support the maintenance of the genera Cleobulia and Cymbosema with their current circumscriptions, but confirmed the polyphyly of Dioclea, with its specie
