Ipomoea leucantha Jacq.

**

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. 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).
