Maximum likelihood phylogeny of angiosperm cox1 introns. The data set includes 71 taxa and 947 nucleotides. Taxa in red are rosids; blue, superasterids; green, monocots; and brown, magnoliids. Numbers above branches are bootstrap support values > 60%, with values > 80% circled. The tree is rooted as described in Sanchez-Puerta et al. (2008).
