Dysoxylum in its new form is essentially Dysoxylum sect. Cyrtochiton, as circumscribed by Mabberley (1995b), and is represented in the phylogenetic tree by clade 6 (Fig. 1B). Didymocheton, Epicharis, Goniocheton, Prasoxylon, and Pseudocarapa are represented by clade 1 (Fig. 1B), clades 4 & 5 (Fig. 1B), clade 8 (Fig. 1B), clade 11 (Fig. 1A) and clade 7 (Fig. 1B), respectively.

This generic resolution is a necessary precursor to detailed monographic work on the genera here recognized. Names are very urgently needed (cf. Heads, 2019) in the countries where these important trees are native and often some of the most frequently encountered and collected. Therefore, a conspectus based on published floristic accounts, which have full descriptions, synonymy and typifications, is presented here. Of the 94 accepted species, those investigated in each recognized genus in this molecular study are listed first, followed by those species that were not. In the interests of conciseness and avoidance of repetition, the descriptions and isotypes and most synonyms of the accepted species are excluded, unless they have not been fully addressed in the recent floristic literature also cited here, so as to allow ready access to the germane literature until definitive monographs are written. Names long-excluded from Dysoxylum s.l. are omitted altogether, as they are also accounted for in that literature.
