Conservation
Using Geocat this species would be classified as Vulnerable (VU) based on its extent of occurrence. However, this is almost certainly an underestimate of the threat. The species is known from three places. Near Santa Rosa de Bocaina only one plant was found; there are no recent records from Cerro Mutún despite several visits during the Darwin Initiative Project 16-004 and it may have become extinct here as a consequence of extensive mining activities; at Santiago de Chiquitos it is still relatively frequent in the cerrados on the plains below the mesetas but these are being rapidly destroyed for housing developments and for “improved” pasture and, unlike Ipomoea psammophila, this species is rare on the mesetas in this area. It should therefore be classified as Endangered (EN) in Bolivia and might even be critically so in the not distant future. Fortunately it also occurs in Brazil and Paraguay but may face similar threats there.
Ecology
A typical plant of the cerrados of Brazil, Paraguay and Bolivia but nowhere very frequent. In Bolivia it is known from three locations in the south of the Chiquitania but is only common around Santiago de Chiquitos. It appears to have subtly different ecological requirements from other cerrado species such as Ipomoea haenkeana or those of the Noel Kempff Park such as I. procurrens.
Morphology General Habit
Erect herb to about 40 cm with a large woody tuberous root, the whole plant densely pilose with rather stiff white hairs swollen at the base Erect species with a characteristic indumentum of long spreading rough hairs covering all vegetative parts as well as the exterior of the corolla
Morphology Leaves
Leaves subsessile, 3 – 8 × 1 – 3.5 cm, oblong – obcuneate, obtuse, base cuneate, both surfaces pilose, green; petioles 0 – 2 mm
Morphology Reproductive morphology Fruits
Capsule 12 × 5 mm, narrowly ovoid, glabrous; seeds 7 × 2 – 3 mm, dark brown, glabrous except for shortly pilose angles
Morphology Reproductive morphology Inflorescences
Inflorescence of solitary (rarely paired), pedunculate axillary flowers arising from the upper leaf axils; peduncles 1 – 4 cm; bracteoles 10 – 25 × 1 – 1.5 mm, linear-lanceolate, finely acuminate, caducous; pedicels 3 – 6 mm; sepals slightly unequal, narrowly ovate, acuminate, pilose, 13 – 16 × 4 mm, inner sepals similar but with broad, glabrous margins; corolla 6 – 7 cm long, funnel-shaped, gradually widened from base, pink, pilose, the hairs with dark bases, limb c. 5 cm diam., shallowly lobed
Note

A very distinct species because of its erect habit, subsessile leaves and stiff spreading hairs which cover almost all parts of the plant including the corolla.

Flowering is stimulated by burning and this species comes into flower as early as September and continues until about January. This is a typical pattern of many cerrado species at Santiago.
