The transition from scalariform-to-simple vessel perforation plates
Flowering plants with simple vessel perforations have evolved from species bearing scalariform perforations but there is a scarcity of integrative studies explaining why these transitions in wood evolution have happened. Lens et al. find that Viburnum, characterised by scalariform vessel perforations (ancestral), diversified earlier than the closely related Sambucus, characterised by simple perforations (derived).
