Subfamily Hyacinthoideae (Hyacinthaceae) comprises more than 400 species, which show distjunct distribution patterns. Ali et al. use dispersal-vicariance and Bayesian binary MCMC analyses to determine that Hyacinthoideae originated in sub-Saharan Africa. The results suggest a bimodal distribution pattern with sub-Saharan Africa as the primary centre of diversity and the Mediterranean region is the secondary centre. Sub-Saharan Africa was the source area for radiation toward Madagascar, the Mediterranean region and India, whilst radiations occurred from the Mediterranean region to eastern Asia, Europe, western Asia and India
