Phylogeny and systematics of Crescentieae (Bignoniaceae), a Neotropical clade of cauliflorous and bat-pollinated trees
<p>The tribe Crescentieae includes <i>Amphitecna</i> (21 species), <i>Crescentia </i>(six species), and <i>Parmentiera</i> (10 species), three genera of understory trees with a center of diversity in Central America and a small number of species in the Antilles and northern South America. Species in Crescentieae are united by their fleshy, indehiscent fruit and cauliflorous, bat-pollinated flowers. The large fruits are presumed to have evolved to be mammal dispersed, although water dispersal is known to occur. To lay a foundation for examining morphological, ecological, and biogeographic patterns within the tribe, we inferred the phylogeny for Crescentieae using both chloroplast (<i>ndhF</i>, <i>trnL-F</i>) and nuclear markers (PepC, ITS). The most recent circumscription of Crescentieae, containing <i>Amphitecna</i>, <i>Crescentia</i>, and <i>Parmentiera</i> is supported by our phylogenetic results. Likewise, the sister relationship between Crescentieae and the Antillean-endemic <i>Spirotecoma</i> is also corroborated by our findings. This relationship implies the evolution of fleshy and indehiscent fruits from dry and dehiscent ones, as well as the evolution of bat pollination from insect pollination. Fruits and seeds from species in Crescentieae are consumed by humans, ungulates, birds, and fish.</p>

FIGURE 6. Clades 1, 2, and 3 and the individual tracks of their respective species. Dotted track represents species from clade 2 (S. neffi (S. giovana + S. guianica)), solid track represent species from clade 3 (S. telson (S. incipiens + S. trichotypa)), and the smaller, dashed track corresponds to species from clade 1 (S. barbosai + S. canabravana). The circle indicates a possible area of vicariance between clade 1 and the remaining two clades.
