It has been suggested that southern Africa is the origin of predominantly herbaceous Apiaceae subfamily Apioideae and woody habit plesiomorphic. We expand previous molecular phylogenetic analyses family by considering all but three approximately 38 genera native to Africa, including whose members, save one, have a habit. Representatives five other are included because they may be closely related these African taxa. Chloroplast DNA rps16 intron and/or nuclear rDNA ITS sequences for 154 accessions analyzed using maximum parsimony, Bayesian, likelihood methods. Within Apioideae, two major clades hitherto unrecognized in inferred. The monogeneric Lichtensteinia clade sister group members subfamily, whereas Annesorhiza ( Annesorhiza, Chamarea , Itasina ) plus Molopospermum (and Astydamia trees) successive except . Tribe Heteromorpheae expanded include Pseudocarum “Oreofraga” ined., endemic Madagascar. corroborated (with subsequent migration northward into Eurasia along dispersal routes), positions within suggest, surprisingly, its ancestor was herbaceous, not woody.
