Trees or shrubs with imparipinnate or bipinnate leaves. Flowers in umbellules or capitula;
Asia-Tropical, Old World tropics present
In Malesia 6 spp., but the section probably includes the majority of the genus in other parts of the Old World tropics.
With the exception of 14. P. philipsonii, the Malesian spp. of sect. Eupteron have umbellules or capitula arranged racemosely along the main inflorescence branches. The type species of the section (P. nodosa) has its flowers in capitula, but this is not considered a sufficient difference to require a separate section.
