The monophyletic status of Ledebouria, Resnova and Drimiopsis (Hyacinthaceae) was investigated using cladistic analyses of morphological characters as well as by combined trnL‐F and morphology dataset. Based on morphology alone, numerous synapomorphies support Ledebouria, Resnova and Drimiopsis as three separate clades. In contrast, trnL‐F data in a reduced taxon sample suggest that Resnova and Drimiopsis are imbedded within Ledebouria, while in combination with morphology again suggest them to be separate. The analysis of morphological data shows that the majority of morphological characters listed by Manning & al. (2004) to support Ledebouria s.l. are homoplasious or symplesiomorphies. A revised taxonomy of Ledebouria, Resnova and Drimiopsis is premature.
