Type
Type: Brazil, Goiás, 17 Jan. 1829, Burchell 8501-2 (holotype BR 0000006972578!, isotype K000612804!, barcode ambiguously placed).
Morphology General Habit
Erect undershrub to 1.5 m, stem woody, hispid-pilose with multicellular hairs, roots tuberous
Morphology Leaves
Leaves subsessile, 3 – 6 × 1.2 – 2 cm oblong-oblanceolate, apex rounded and mucronate, base cuneate and slightly asymmetric, adaxially densely grey-pubescent, abaxially hispid-hirsute and gland-dotted, petioles 0 – 5 mm
Morphology Reproductive morphology Inflorescences
Inflorescence terminal, simple, short to somewhat elongate, formed of shortly pedunculate cymes from the uppermost leaf axils; peduncles 0.5 – 1 cm, diminishing in size upwards; bracteoles up to 6 × 2 mm, linear-lanceolate, caducous; pedicels 3 – 5 mm so cymes congested; sepals similar, 5 – 7 mm, ovate-elliptic, obtuse, grey-tomentellous, slightly accrescent in fruit; corolla 4 cm, funnel-shaped, pink, appressed pilose, limb c. 3 cm diam., shallowly lobed
Morphology Reproductive morphology Fruits
Capsule c. 10 × 6 mm, narrowly ovoid, glabrous; seeds woolly.
Ecology
Scattered through the cerrados of central Brazil, this species is only known from cerrado or campo humedo near Flora d Oro in the Noel Kempff Mercado National Park very close to the Brazilian border.
Conservation
The Bolivian population is an outlying colony from the main populations in Brazil. No information is available about the size of the Bolivian population but it lies within a protected area and faces no current, obvious threat. Without further information it can only be classified as Data Deficient (DD).
Note

Close to Ipomoea haenkeana but leaves < 2 cm wide, densely pubescent adaxially and inflorescence simple, side branches absent or very short.

Found in flower in Bolivia at the end of the summer rainy season.
