Abstract
The Tradescantia alliance (subtribes Tradescantiinae and Thyrsantheminae of tribe Tradescantieae, family Commelinaceae) comprises a group of closely related New World genera exhibiting considerable morphological, life history, and genomic traits. Despite ecological and cytogenetic significance, phylogenetic relationships among genera and species remain uncertain. In particular, variation in inflorescence morphology has confounded classification and taxonomy. The presence of self compatible and incompatible species allowed us to test the hypothesis that self compatible species will have condensed inflorescences. We constructed a molecular phylogeny for 85 taxa in Commelinaceae, with sampling focused in the Tradescantia alliance. Constraint tests supported only subtribe Tradescantiae, Tripogandra and Tinantia as monophyletic with Tripogandra nested within Callisia. We estimated ancestral states for both breeding system and inflorescence condensation and tested for correlation. Inflorescence morphology, an important character for generic identification, is more labile than previously expected, with condensed inflorescences evolving twice with three subsequent reversals. Breeding system evolution is more complex, with many more switches between self compatible and incompatible and more uncertainty in ancestral state estimates. While we did not find correlation between self compatibility and inflorescence condensation, we propose additional floral and inflorescence characteristics which may have contributed to variation in breeding system.
