Ipomoea leucantha Jacquin. Whitestar Morning-glory. Phen: Jul-Dec. Hab: Disturbed areas, roadsides. Dist: "Occurs sporadically, principally in the eastern United States and in
Central America south to Ecuador and Brazil" (Wood et al. 2020).
ID notes: This species seems best identified by its glabrous sepals (Felger et al. 2012), in comparison to the similar species I. cordatotriloba, I. lacunosa, and I. triloba.
Origin/Endemic status: Native
Taxonomy Comments: This species had been thought to originate from a cross between I. cordatotriloba and I. lacunosa. However, Duncan & Rausher (2013) found that I. leucantha was not interfertile with I. lacunosa. It is widespread and fecund (Felger et al. 2012) necessitating its recognition as a species (Duncan & Rausher 2013). Another genetically similar entity was given the provisional name Ipomoea austinii (non I. austinii Infante-Bet.), but was not formally described (Duncan & Rausher 2013)." (Atlas of Florida Plants 2018).
