  • Molecular phylogenetic studies have shown that the evolutionary history of Geum L. has been strongly influenced by allopolyploidy, and they have indicated widespread homoplasy in morphological traits within the group. This study of gynoecial development in Colurieae shows that fruits with jointed styles develop similarly. In early stages of development, the position of the joint is basal in all lineages where it is present. In the diploids, it remains at the base of the style, but in the… CONTINUE READING
