Three plastid regions-the rps16 intron, the atpB-rbcL intergenic spacer, and the trnL-F region-in 73 taxa representing all the genera of Colchicaceae except Kuntheria were sequenced to investigate the intrafamilial relationships of the family. In total, the three gene regions, comprising 3830 characters, were analyzed both separately and in a combined matrix. The results did not support the division of the family into two subfamilies, but they did support a core clade of mainly African genera and a grade of Australian, North American, and Asian taxa. One of the four tribes, Iphigenieae, was grossly paraphyletic, and, unexpectedly, Colchicum was nested within Androcymbium. Further, taxa of Gloriosa and Littonia were intermixed.
