The Tribe Condamineeae, as circumscribed by Kainulainen et al. (2010), belongs to Subfamily Ixoroideae and includes about 32 or 33 morphologically diverse genera with perhaps 150 species. Most of the genera are endemic to the Neotropics, but the tribe is also found in warm temperate Asia (Emmenopterys), warm temperate North America (Pinckneya), and the Pacific region (Dolicholobium, Mastixiodendron, and Mussaendopsis). Plants of Condimineeae are woody, and range from monocaulous shrubs to large trees, some of the canopy emergents. Raphides are absent. The inflorescences are generally cymose and variously axillary and terminal. The flowers are mostly hermaphroditic though Dioicodendron and Dolicholobium are dioecous. The hermaphroditic flowers are protandrous or in a few cases protogynous (Alseis, Chimarrhis, Warszewiczia), with this floral biology consistent at the genus level. The fruits are mostly dry and capsular with numerous seeds that are variously angled to flattened and winged, but are baccate, fleshy, and indehiscent in several genera (Bothriospora, Hippotis, Pentagonia, Pogonopus, Tammsia). Species of a number of genera have well developed calycophylls. Corolla lobe aestivation varies, as does stipule form. Several genera have quite unusual features for Rubiaceae, in particular Dialypetalanthus has free petals and numerous stamens and was treated for a long time in its own family, Dialypetalanthaceae. Overall as discussed by Kainulainen et al. the Tribe Condamineeae is difficult to characterize morphologically.

The circumscription of the Tribe Condamineeae has been varied and problematic, and some of its genera were classified very differently by different authors until the analysis of Bremer & Eriksson (2009) found a clearly circumscribed group within the Subfamily Ixoroideae. This monophyletic Tribe Condamineeae was then studied in more detail by Kainulainen et al. (2010). Before these studies the classification of the genera of Tribe Condamineeae was based on morphological features, and these were not all grouped together and were included in various other tribes. Andersson (1995) studied in detail the capsular-fruited genera that had been included in tribe Cinchoneae, and he separated some of the into the recently described Tribe Calycophylleae. Molecular data eventually clarified the systematics of this group, and Bremer & Eriksson showed that Calycophylleae and Condamineae form a monophyletic group in Subfam. Ixoroideae.

Although the Tribe Condamineeae is now rather clearly circumscribed, the delimitations and relationships of the component genera are far from understood. Kainulainen et al. (2010) sampled the potential member genera of the tribe well but had relatively few species of many of them. They and found several genera that are possibly or clearly not monophyletic, but their analysis adequately support only three taxonomic rearrangements, the resurrection of a monotypic genus, the synonymization of another monotypic genus, and the transfer of six species from one genus to another that they also resurrected. This study found several additional genera or groups that need general review, and many genera remain to be studied in detail. Most of the genera of Tribe Condamineae have never been comprehensively reviewed.
