Abstract

Distributional patterns of the genera of Euphorbiaceae were analyzed under a panbiogeographic approach, using the parsimony analysis of endemicity (PAE) method. Four generalized tracks were obtained, joining the following regions: (1) Neotropical-Afrotropical (determined by the genera Amanoa, Caperonia, Conceveiba, Manprounea, Pogonophora, Savia and Tetrorchidium); (2) Temperate  Australian-Tropical Australian-Neoguinean-Oriental (determined by the genera Actephila, Baloghia, Choriceras, Petalostigma and Sauropus); (3) Temperate Australian-Tropical Australian-Neoguinean-Afrotropical- Neotropical (determined by the genera Acalypha, Alchornea, Cleidion, Drypetes, Margaritaria, Microstachys, Omphalea and Phyllanthus); and (4) Neoguinean-Oriental-Afrotopical (determined by the genera Glochidion, Macaranga, Microdesmis and Shirakopsis). Two generalized tracks overlap in the Afrotropical region, which is identified as a node.
