About ALBUCA - name changes explained

“A molecular phylogeny and a revised classification of Ornithogaloideae (Hyacinthaceae) based on an analysis of four plastid DNA regions” written by John C. Manning, Félix Forest, Dion S. Devey, Michael F. Fay & Peter Goldblatt in TAXON 58 (1), February 2009: 1-107,
Three clades are identified. Clade A is recognized as the genus Albuca with a well-defined green or brownish median longitudinal band on the outer surface of each tepal and a concentration of 3-5 veins along the midline. Clade B comprises the genera Dipcadi and Pseudogaltonia. Clade C is the genus Ornithogalum and includes Galtonia and Neopatersonia, these genera have uniformly colored tepals with at the most a narrow or indistinct darker band without the veins. This means that species that were previously considered to belong in Ornithogalum are now included in Albuca and vice versa
