Validation of several species names in Hyacinthaceae

Abstract

Hyacinthaceae includes many taxa of hysteranthous or proteranthous plants, in which leaves and inflorescences are not coetaneous. Many herbarium sheets of such taxa, including type specimens, were prepared with samples gathered at different times to include as many vegetative and reproductive structures as possible to facilitate future identification. As a result of our taxonomic work being undertaken on several genera of the family, we found that holotypes of 14 taxa include different gatherings and are therefore not validly published, according to Art. 8.2 of the Melbourne Code. Validation of those names is effected in the same genera and ranks as they were first described, and a brief discussion is added for each case. Furthermore, four additional names are discussed in which a conclusive interpretation about invalid publication is not possible according to the available data, and hence their acceptance as valid names is here suggested.
