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 has 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 to the apex of teeth) shorter than free filaments (7–8.5(–10) mm long).
- U. amazonica has 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 to the apex of teeth) longer than free filaments (6.5–8(–10) mm long).
U. × grandiflora has shorter leaf blades, slender free filaments, and staminal cups shorter than free filaments.
U. amazonica has longer leaf blades, flat free filaments, and staminal cups longer than free filaments.
