Urceolina is a genus of South American plants in the amaryllis family native to Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Guatemala, Panama, and Peru.
[2][3] It has also been introduced to many South and Central American states, as well as India and Sri Lanka.
However, Herbert's name was illegitimate since the genus name had already been published in 1786 when it was attributed to Juan Ignacio Molina.
This is now a conserved name with the type species being Urceolina urceolata based on Crinum urceolatum.
A 2020 molecular phylogenetic study showed that these two genera (excluding C. korsakoffii) form a monophyletic clade with Urceolina sensu stricto, sister to Stenomesson:[6] Rauhia Plagiolirion Phaedranassa Eucrosia Stenomesson Urceolina, Eucharis, most of Caliphruria, and Eucrosia dodsonii The clade showed extensive ancestral reticulation.
