![]() ![]() The combination of data yielded phylogenetic trees with 31 well‐defined clades or lineages, most corresponding to previously described genera, although some have required description or revised circumscription. Bayesian Inference (BI), Maximum Likelihood (ML), and Maximum Parsimony (MP) analyses were performed to derive the phylogenetic patterns. ![]() Here we present phylogenetic analyses involving four plastid DNA regions (trnL intron, trnL‐F spacer, matK and trnCGCA‐ycf6 intergenic region), a nuclear region (Agt1) and a selection of 40 morphological characters. Some authors have recognised only two genera, with a very broadly conceived Drimia, while others have accepted several genera which, although better defined morphologically, were doubtfully monophyletic. The taxonomy and systematics of Urgineoideae (Hyacinthaceae) have been controversial in recent decades with contrasting taxonomic treatments proposed based on preliminary and partial studies that have focused on morphology and/or solely plastid DNA sequence data. ![]()
