- 1. Frank Hauenschild, & David J. Mabberley & Department of Molecular Evolution and Plant Systematics & Herbarium (LZ), Institute of Biology, Leipzig University, Leipzig, 04103, Germany & intergenic spacer support this hypothesis. Six strongly supported clades within Dysoxylum s. l. were recovered, in large part supporting the classification of Harms. Based on the largest molecular phylogenetic tree hitherto assembled, and morphological considerations, a revised disposition of 94 currently recognized Dysoxylum species, is presented, reinstating the genera Didymocheton, Epicharis, Goniocheton, Prasoxylon and Pseudocarapa. The first valid publication of the generic name Dysoxylum is identified, and it is typified with D. macrocarpum. Forty-three new combinations at species level and two at infraspecific are proposed; Didymocheton nutans, Dysoxylum alatum, D. pachyphyllum, Epicharis, Trichilia spectabilis and T. alliacea (second step) are lectotypified.
