A summary tree showing phylogenetic relationships among asterid families. Red pentagrams represent support of 100% in all six trees. For other branches, green triangles, purple rhombuses, and blue squares represent support of ≥90%, ≥80%, and ≥70% in at least four trees, respectively. Yellow circles indicate nodes with alternative topologies. Family names are given at the terminals, with order names to the far right. Names representing paraphyletic or polyphyletic groups are given in purple. (See figures 2–5 for detailed phylogenetic relationships among terminal taxa in various groups.)
