The trees were constructed with Bayesian inference posterior probability/maximum parsimony, which are given on each branch; maximum likelihood is below branches. *Maximum support in all three analyses or maximum support value for only one or two methods. Morphological characteristics of five selected features were used to evaluate the three evolutionary lineages. The testa characteristics of species selected as outgroup [Nothoscordum bivalve, Tulbaghia violacea were taken from Kruse (1986)].
