A species scattered in seasonally dry tropical forests below 1000 m in South America, most common in the Chiquitano dry forest of eastern Bolivia, around Guayaquil (Ecuador) and in northern Colombia and Venezuela. Previously known as Turbina abutiloides (Kunth) O’Donell, this formerly recognised genus is now treated as a synonym of Ipomoea.
