Resumen: Sapium is reduced from ca. 100 spp. to just 21. As defined here, the genus is restricted to the Neotropics. Those Old World spp. previously included in Sapium are now apportioned among four other genera, three of which are mentioned in the title of the revision. As lumping is the theme, at the sp. level, this work features no novelties in Sapium. Five spp. are apparently attributable to Costa Rica (it is difficult to be certain, since the "Distribution" statements are general and incomplete, and there are no exsiccatae citations). All but one (S. pachystachys Pittier) are henceforth to be known under regionally unfamiliar names: S. glandulosum (L.) Morong (incl. S. aucuparium Jacq., S. oligoneurum K. Schum. & Pittier, S. jamaicense Sw.); S. laurifolium (A. Rich.) Griseb. (incl. S. aucuparium sensu Flora of Panama non Jacq., S. pleiostachys K. Schum. & Pittier); S. macrocarpum Müll. Arg. (incl. S. thelocarpum K. Schum. & Pittier); and S. stylare Müll. Arg. (incl. S. rigidifolium Huft). [N.B.: our data-base has long since incorporated these changes from Kruijt's (1989) Utrecht thesis.] Features separate dichotomous keys to vegetative and flowering specimens, plus a synoptical key, detailed line -drawings of all spp., photographs of lvs., and an index to exsiccatae. A phylogenetic analysis of Sapium and related genera employs 47 conventional (morphological) characters
