Yet component, three-area-statements, and Brooks parsimony analysis suggest that Tertiary history has little influenced the distribution of these genera. Widespread taxa and composite areas may mask Early Tertiary influences, or the two genera may have a more recent history on these islands. Alternatively, nucleotide diversity, evolutionary rates, and coalescent analyses of molecular phylogenies all suggest the antiquity of the Pictetia and Poitea radiations. Molecular biogeographic approaches are used to identify and estimate the ages of these endemic Tethyan radiations. The results are corroborated by confirming a species-area disequilibrium among the legume floras for islands of the world. Age of island biota and area of island are both needed to most accurately predict numbers of endemic legume taxa. The findings presented here combined with the legume fossil record suggest that both Pictetia and Poitea stem from Early Tertiary North American boreotropical ancestors. Thus, Wolfe's hypothesis that the Greater Antilles harbor boreotropical relicts finds support.} }
