The taxonomy of subfamily Ornithogaloideae (Hyacinthaceae) has been a matter of controversy in recent decades, with several contradictory taxonomic treatments having been proposed. Martínez-Azorín et al. present a phylogenetic analysis of Ornithogaloideae based on a combination of plastid and nuclear regions and a detailed morphological study. A new taxonomic arrangement is presented in which 19 clades are recognized as genera, well defined by clear morphology and biogeography. Over 100 new combinations are made and two new names are proposed to accommodate the taxa in the new arrangement.
