abstract = {Bird pollination is relatively common in the tropics, and especially so in the Americas. In
the Neotropical tribe Myrteae (Myrtaceae), species of two genera, Acca and Myrrhinium,
offer fleshy, sugary petals to the consumption of birds that otherwise eat fruits, thus
pollinating the plants in an unusual plant-animal interaction: fruit-bird ornithophily. The
phylogenetic position of these genera has been problematic, and so it was the
understanding of the evolution of this interaction. Here we include new sequences of
Myrrhinium atropurpureum in a comprehensive molecular phylogeny based on two plastid
and two nuclear markers, with the aim of providing the historical framework of the fruitbird
ornithophily syndrome. We developed and scored 13 flower and inflorescence
characters that depict the macroscopic morphological components of this syndrome.
Bayesian and parsimony phylogenies concur in placing both Acca and Myrrhinium in a
clade with Psidium species; with Myrrhinium sister to Psidium. Mapping of morphological
characters indicated some degree of convergence (e.g., fleshy petals, purplish display) but
also considerable divergence in key characters that point to rather opposing pollination
strategies and also different degrees of specialization in Acca versus Myrrhinium. Fruit-bird
ornithophily represents a special case of mutualism that highlights the evolutionary
complexities of plant-animal interactions}
