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, free filament shape, and staminal cup length:^[2]

U. × grandiflora have shorter leaf blades (20–33 cm × (10–)13–16 cm), linear or narrowly subulate free filaments (1–1.5 mm wide at the base), and staminal cups (5–7 mm long) shorter than free filaments (7–8.5(–10) mm long).
U. amazonica have longer leaf blades ((20–)30–40(–50) cm × (10–)12–18 cm), subulate free filaments (2.8–3.4 mm wide at the base), and staminal cups (11.2–13.8 mm long) longer than free filaments (6.5–8(–10) mm long).

U. × grandiflora has short leaf blades, slender free filaments, and staminal cups shorter than free filaments.
U. amazonica has long leaf blades, flat free filaments, and staminal cups longer than free filaments.
