The tribe Pauridiantheae comprises 5 genera and ca. 40 species. It is an essentially tropical African tribe, only one species is endemic in Madagascar. The Pauridiantheae are shrubs or small trees characterised by entire interpetiolar stipules, axillar or more rarely terminal infloescences, often small heterostylous flowers with valvate corolla lobes, and an inferior ovary with 2-5 locules. The small seeds are numerous and the exotesta is strongly thickened. Pollen is 3-colporate. The present study wants to complete a revision of the genus Pauridiantha. Antomical, pollen morphological and chorological characters will be used in the delimitation of species. The relation between Pauridiantha and its closest allies will be studied in future.
