Additional file 11: Table S3. of Clock-dated phylogeny for 48% of the 700 species of Crotalaria (Fabaceae–Papilionoideae) resolves sections worldwide and implies conserved flower and leaf traits throughout its pantropical range

Species list with coding of sections, distribution areas, leaf and flower trait states, species’ climate categories, number of GBIF records, and chromosome numbers. Polhill’s [45] sections (1 = Grandiflorae, 2 = Chrysocalycinae, 3 = Hedriocarpae, 4 = Geniculatae, 5 = Schizostigma, 6 = Calycinae, 7 = Crotalaria, 8 = Dispermae); Le Roux et al.
