Taxonomy

Salisbury originally described the Omphalissa as a subgroup of the Zephyrantheae, then a tribe within the Amaryllidaceae, in which he included Amaryllis (now Hippeastrum) aulica and A. calyptrata. This was subsequently more formally defined by John Gilbert Baker in 1888, as a subgenus of Hippeastrum with six species.[6] Baker's six species were;
