abstract = {The Metastelmatinae (Asclepiadoideae, Apocynaceae) include 13 genera and approximately 260 species with complex morphological affinities that are broadly distributed in the Neotropics. This study investigated phylogenetic relationships within this subtribe using
plastid (trnT-F, trnS-G, trnH-psbA, trnD-T, rps16, and matK) and nuclear (ITS) markers. The taxonomic sampling focused on the South
American species, and included approximately 25% of the subtribe. Individual data partitions, and combined datasets were analyzed using
Bayesian inference, maximum likelihood, and maximum parsimony. The results indicated that most genera of Metastelmatinae are not
monophyletic. Internal relationships in the subtribe and key morphological characters used in the taxonomy of the group are discussed. The
lack of resolution in the molecular phylogeny, incongruent phylogenetic signals between plastid and nuclear datasets, and the lack of
morphological features for individual clades prevented major taxonomic changes in this group, those of which were restricted to the inclusion
of Barjonia harleyi and Hemipogon harleyi into Minaria forming the new combinations Minaria harleyi and M. volubilis, and the synonymy of
Macroditassa under Peplonia with the new combinations Peplonia adnata and P. macrophylla.}
