Type
Brazil, Bahia, Blanchet 564 (lectotype G-00222101, designated by Buril & Staples 2018: 2, isolectotype BM-001217799).
Morphology General Habit
A nearly glabrous twining plant with ovate, cordate, acute and mucronate leaves
Morphology Reproductive morphology Inflorescences
Inflorescence somewhat lax, usually clearly cymose rather than umbelliform, often 6 – 15-flowered; peduncles commonly < 6 cm long; bracteoles linear-filiform, 1 – 3 mm long, inconspicuous; pedicels mostly 5 – 6 mm; sepals completely glabrous, 3 – 4 mm long, rounded to obtuse, outer a little shorter than inner sepals
Morphology Reproductive morphology Flowers Corolla
Corolla 1.5 – 2.3 cm, pale blue, occasionally white.
Distribution
Endemic to southern South America, this is a lowland species usually found below 800 m but exceptionally reaching 1450 m in Bolivia. It is locally common in parts of northern Argentina, Paraguay, southern Bolivia and south and central Brazil. It becomes less common in the north of its range in northern Bolivia and Peru and appears to be absent from the Amazon basin and most of NE Brazil as well as Ecuador, Colombia and Venezuela.
Conservation
Least Concern, even in Peru based on the wide extent of occurrence, exceeding the IUCN threatened threshold for criterion B.
