“…-Our molecular phylogenetic study provides the first in-depth sampling of African Melastomateae including most genera (10/13) and approximately 42% of the species. With this dense sampling, we succeeded to recover as monophyletic several genera, subgenera and sections that have been suggested in earlier systematic treatments based on morphology (Bentham, 1849;Fernandes & Fernandes, 1969;Jacques-Félix, 1981, 1995 Table 1; Figs. 1-4; Electr.…”

“…ex DC. (now Aciotis) was suggested as its closest relative (Bentham, 1849). It was later treated in Bertolonieae because its seed anatomy and geographic distribution are similar to those of African Ochthocharis G.Don (Van Tieghem, 1891).…”

“…On the basis of this morphological diversity, several generic and infrageneric classification schemes have been proposed (Table 1) for African Melastomateae (Bentham, 1849;Naudin, 1850Naudin, , 1853Triana, 1872;Cogniaux, 1891;Fernandes & Fernandes, 1969;Jacques-Félix, 1981, 1995Van Vliet & al., 1981). Bentham (1849) recognised only four genera: Heterotis Benth., Dissotis, Tristemma Juss. and Osbeckia L., and he proposed the first infrageneric classification of Heterotis with four sections, though only two of them (sect.…”

“…While most genera of African Osbeckieae (Melastomateae) have always been placed in this tribe, the positions of Dinophora and Guyonia remain controversial. Dinophora has been treated in Rhexieae (Bentham, 1849), Bertolonieae (Van Tieghem, 1891), Melastomateae (Triana, 1872;Baillon, 1877;Cogniaux, 1891;Gilg, 1898;Engler, 1921;Renner, 1993;Stevens, 2001-) and Dissochaeteae (Jacques-Félix, 1983, 1995Leistner, 2005). Several authors have treated Guyonia within the Old World Melastomateae (Triana, 1872;Van Tieghem, 1891;Krasser, 1893;Engler, 1921;Renner, 1993).…”

Melastomateae are the most species-rich (185 spp./13 gen.) and morphologically diverse tribe within the African Melastomataceae. In this study we present the first in-depth phylogenetic analysis of African Melastomateae using sequences generated from one nuclear (nrITS) and two plastid spacers (accD-psaI, psbK-psbL) sampling 183 accessions representing 75 African, 10 Madagascan and 7 Asian species and a broad outgroup sampling. We infer phylogenetic relationships using maximum likelihood, maximum parsimony and Bayesian approaches and propose a revised generic classification of African Melastomateae based on our molecular trees in combination with a careful reassessment of morphological variation. Our phylogenetic analyses support the monophyly of Old World Melastomateae except Dinophora which clearly falls outside Melastomateae. Asian and Madagascan endemic genera of Melastomateae are nested among the African genera. Of the African genera only two monophyletic groups, Dichaetanthera and Tristemma, are recovered in addition to the monospecific Pseudosbeckia lineage, while Antherotoma, Dissotis and Heterotis as currently circumscribed are polyphyletic. However, the subgenera and sections of these genera are mostly recovered as morphologically distinct and molecularly well-supported clades. Isomorphism versus dimorphism of the stamens is found to be an unreliable character when delimiting genera in Melastomateae. We propose the reinstatement of Argyrella and Dupineta, a new status at generic rank for Dissotis subg. Dissotidendron, a broadened circumscription of Guyonia (to include the species previously placed in Heterotis sect. Cyclostemma), and description of a new, monospecific genus Anaheterotis for the Heterotis pobeguinii lineage. Heterotis is maintained at generic rank but with a narrower circumscription in comparison to earlier treatments. We accommodate the rare Osbeckia porteresii lineage from Mt. Nimba (Guinea) within an expanded Melastomastrum. To complete our generic realignment, a total of 42 new combinations are effected at the species level and below, and a key is provided for the 12 genera presently recognised in African Melastomateae. Denser taxonomic sampling and sequencing of more loci will be needed to resolve relationships within the large clade of Dissotis s.str. and allies (including Antherotoma as well as three West African species erroneously placed in the otherwise Asian Osbeckia).
