'''''Urceolina'' × ''grandiflora''''', formerly known as '''''Eucharis'' × ''grandiflora''''', is a [[natural hybrid]] putatively between ''[[Urceolina moorei|U. moorei]]'' and ''[[Urceolina sanderi|U. sanderi]]'' of the [[family (biology)|family]] Amaryllidaceae, [[native plant|native]] to western [[Colombia]] and western [[Ecuador]].<ref name="Kew">{{Cite web|title=''Urceolina'' × ''grandiflora'' (Planch. & Linden) Traub|url=http://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:261579-2|access-date=2023-06-28|website=Plants of the World Online|publisher=Kew Science}}</ref>

The [[Aneuploidy|aneutriploid]] species ''[[Urceolina amazonica|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:<ref name="Meerow, 1989">{{Cite journal |last=Meerow |first=Alan W. |date=1989 |title=Systematics of the Amazon lilies, ''Eucharis'' and ''Caliphruria'' (Amaryllidaceae) |url=https://www.jstor.org/stable/2399347 |journal=Annals of the Missouri Botanical Garden |volume=76 |issue=1 |pages=136–220 |doi=10.2307/2399347 |jstor=2399347 |issn=0026-6493}}</ref>
* ''U.'' × ''grandiflora'' has shorter leaf blades (20–33&nbsp;cm × (10–)13–16&nbsp;cm), linear or narrowly [[Glossary of leaf morphology#subulate|subulate]] free [[stamen|filaments]] (1–1.5&nbsp;mm wide at the base), and staminal cups (5–7&nbsp;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&nbsp;cm), subulate free filaments (2.8–3.4&nbsp;mm wide at the base), and staminal cups (11.2–13.8&nbsp;mm long to the apex of teeth) longer than free filaments (6.5–8(–10) mm long).
