Narcissus bujei

Narcissus bujei has had a chequered history. It is considered an ancient hybrid of N. pseudonarcissus where they overlap with species from Nevadensis. It was first described as N. longispathus var. bujei Fern. Casas, then as a variety of N. hispanicus, then a subspecies of N. hispanicus and then as a separate species, all by Fernandez Casas at various times. Although still listed as a synonym of N. longispathus on the World Checklist, its species rank was confirmed by Zonneveld on the basis of DNA content (30 vs. 36 pg) and included in the new Section Nevadensis, distinct from Pseudonarcissus, being from southern Spain with a DNA content of 30–39 pg. An alternative spelling of Narcissus bugei is accepted. == References ==
