Evolution of gynoecium morphology in Old World Papaveroideae: a combined phylogenetic/ontogenetic approach.

Premise Of The Study: The correct assessment of homology is an important prerequisite for reconstructing phylogenetic relationships and character evolution. Old World Papaveroideae (Papaver, Meconopsis, Roemeria, Stylomecon) show substantial diversity in gynoecium and capsule morphology. In particular, capsules can have distinct styles (Meconopsis p.
