A Super-Matrix Approach to the Bignoniaceae Phylogeny.

Bignoniaceae, also known as the trumpet creeper family, consists of 800 species of trees, shrubs, herbs, and lianas. Bignoniaceae diversity is highest in the Neotropics, but have a worldwide distribution in both tropical and temperate zones. Molecular phylogenetic studies recognize 8 major clades in the family. The goal of this work is to construct an updated Bignoniaceae phylogeny by gathering all available DNA sequence data in the family from previous studies, GenBank, and unpublished sources. Phylogenetic reconstruction of the concatenated data was done using Maximum Likelihood and Bayesian methods. With these results, we aim to better understand family-wide diversification patterns in the family. Previously recognized clades are supported, additional resolution among them is obtained, and major biogeographic events are reconstructed.
