Originally described by Richard Anthony Salisbury in 1866.[6] DescriptionRobust habit, two to four large flowers. Perianth with a short tube(< 4 cm), paraperigonium curved closing the throat by a distinct neck. Stigma trifid or capitate, lobes > 2 mm. Spathe slit to the base. Ribbon-like leaves, 2.5 to 5 cm broad. Many dry, flat seeds.[1][7][8] TaxonomySalisbury 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.[7] Baker's six species were;
