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).
