Urceolina × grandiflora, formerly known as Eucharis × grandiflora, is a natural hybrid putatively between U. moorei and U. sanderi of the family Amaryllidaceae, native to western Colombia and western Ecuador.[1]
The aneutriploid species U. amazonica is often misidentified as U. × grandiflora. Both of them are sterile plants with large fragrant white flowers, but they differ in leaf length, staminal cup length, and free filament shape: U. × grandiflora have shorter leaf blades of 20–33 cm (versus (20–)30–40(–50) cm of U. amazonica) and shorter staminal cups of 5–7 mm (versus 11.2–13.8 mm of U. amazonica), and its free filaments are linear or narrowly subulate (versus subulate of U. amazonica) and 1–1.5 mm wide at the base (versus 2.8–3.4 mm of U. amazonica).[2]
