• Resumen

  • The taxonomic history of Zephyranthes andina (= Haylockia andina) and five related taxa is analysed. The study of herbarium material and photographs, and observation of live plants in the field and in cultivation allowed an evaluation of the variation of flower characters, such as style length, used by other authors for taxonomic delimitation of Z. andina and five additional species, three published in Zephyranthes and two in Haylockia. A lectotype for the name Haylockia andina is designated. Five names are reduced to synonymy. The generic position of the single taxon is discussed. The first chromosome counts (2n = 20), a distribution map, phenological data, an evaluation of its conservation status and ample photographic illustration of flowering plants in nature and in cultivation are provided.
