Systematics of Sabiaceae and Neotropical Meliosma.

The family Sabiaceae includes three genera, Meliosma, Ophiocaryon and Sabia, the first one being the largest with more than 100 species. The family displays a Southeast Asia-Neotropics disjunct distribution, and Meliosma is the only genus that is found in both continents.The most recent taxonomic treatment for any member of the family was done in1981 for Sabia, and Meliosma was last monographed in 1971, but this study did not include the Neotropical species. To date, no phylogenetic studies have focused exclusively on Sabiaceae, but previous studies that included few taxa of this family have placed it among basal eudicots. Data from plastid loci have been generated for multiple taxa in Sabiaceae with the objective of elucidating genus-level relationships within the family. Likewise, plastid loci and nuclear ITS data have been gathered to investigate relationships at the species level within Meliosma. Preliminary results support a basal position of Sabia within the family and revealed various well-supported clades including one that only includes Andean species of Meliosma.
