Conteúdo: | The structural characteristics of quinolizidine alkaloids have been quantified on the basis of their biogenetic origins. Such data have been used do determine evolutionary advan- cement parameters for genera of the Papilionoideae. These analysis indicate a correlation of the structural characters of alkaloids with ecogeography and morphology of the genera, suggesting an adaptive radiation of the taxa from tropical Africa in the three major direc- tions along a southern temperate "pre-cytisine" route, a northern temperate "pre-cytisine- cytisine" route and a tropical "ormosanine" route with a temperate cytisine branch. The data also suggest the division of the Sophoreae into three chemical groups giving rise to Liparieae, Genisteae, Thermopsidae and Bossiaeeae. These concepts are embodied in a tentative phyletic classification of all genera of the Papilionoideae which contain quinoli- zidine alkaloids.
