中文摘要	Phenetic analysis of the New World Jatropha L. species generally supports the 1979 classification of the genus by Dehgan and Webster. The distinctness of subgenera Curcas (Adans.) Pax and Jatropha, the intermediate position of section Polymorphae Pax between sections of both subgenera, and the close relationship of sections Mozinna (Ortega) Pax and Loureira (Cav.) Muell. ex Pax are indicated. Phylogenetic analysis provided evidence of monophyly for subgenus Jatropha, sectioris Jatropha and Mozinna, and probable paraphyly in subgenus Curcas and several sections arid subsections. The cladistic analyses described herein produced multiple parsimonious topologies. The circumscriptions of the subgenera and some sections and subsectioris are significantly clarified. The status of heretofore dubiously placed or recentlv described species is also elucidated. Although geographical data were not included in the phylogenetic analyses, a district correlation between evolutionary trends in morphological features, postulated infrageneric delimitations, arid geography of the genus became evident. Eviderice is presented to support the antiquitv of the genus and its present distribution, which resulted from a Gondwanaland breakup and subsequent overland dispersal across the African and American continents. Adaptive gradual mosaic evolution as a series of successive speciationat steps, primarily involving inorphological features, in concert with migration to areas of increasing aridity and cold appears to be the norm for the genus.
