 | | Roughly 500 accessions were sampled from major tribes of the Strychnaceae, Loganiaceae, Gelsemiaceae, Gentianaceae, Apocynaceae s.l., and Rubiaceae. |
 | | Gelsemiaceae is supported as a distinct family and is unresolved along with Strychnaceae-tribe Antonieae and Rubiaceae. |
 | | Surprisingly, Gentianaceae is in the basalmost position; it is also the only family (except for tribes Antonieae and Spigelieae in the Strychnaceae) that lack alkaloids. |
