    Type
    Types: Brazil, Goyas et Pianhy, G. Gardner 3356 (lectotype BR 0000005837519!, designated here, isolectotype K!).
    Habit
    Erect perennial, stem stout and somewhat woody, often simple, white-tomentose, 0.3 – 1 m high
    Leaves
    Leaves subsessile, 2.5 – 10 (– 14) × 2 – 3.5 (– 5.5) cm, broadly oblong to oblong-elliptic, acute and sometimes mucronate, cuneate to rounded at base, densely sericeous or tomentose on both surfaces, upper surface greenish, lower surface grey; petioles 0 – 5 mm
    Inflorescences
    Inflorescence terminal, formed of sessile or shortly pedunculate compact cymes from the upper leaf axils, cymes commonly single-flowered but sometimes with 2 – 10 flowers; peduncles 0 – 2.5 cm, tomentose; bracteoles linear-lanceolate to ovate, up to 10 × 5 mm, hirsute, somewhat persistent; pedicels 1 – 3 mm; sepals subequal, 7 – 9 mm, elliptic, obtuse, coriaceous, concave, brown when dry, the outer villous but glabrescent, inner glabrous; corolla 5 – 6 cm, funnel-shaped, pink, glabrous, limb c. 4 cm diam., distinctly lobed
    Fruits
    Capsule glabrous, ellipsoid, 8 × 6 mm, very shortly rostrate; seeds c. 3 mm, long-pilose
    Ecology
    A characteristic species of cerrado in Brazil extending to Paraguay, Brazil and to the llanos of Venezuela and Colombia. In Bolivia it is common in rocky cerrados on and below the meseta in the Noel Kempff Park but only known elsewhere from Cerro Pelón near Santo Corazón.
    Conservation
    Data Deficient but probably Least Concern (LC). In Bolivia this species is only known from two protected areas, the PN Noel Kempff Mercado and the ANMI San Matías. It appears to be common in the former, particularly on the vast, inaccessible meseta, while the Serranías de Sunsas are so poorly known that it is impossible to speculate about its frequency in this region from a single collection.
    Note

    A very distinct species for its erect habit, subsessile silvery leaves and lobed corolla.

    It flowers principally at the onset of the first rains in October and November but may be found flowering sporadically at other times.

    Meisner cited two syntypes, Gardner 3356 and Spruce 3605. Of these two we have selected Gardner 3356 (BR) as lectotype as it is the only one represented in Martius’ herbarium. It is also the most similar to the common form of this species in Brazil which is similar to the plant from Santo Corazón (Fig. 22B) whereas the Spruce specimen has more sericeous leaves similar to the form from the Noel Kempff Park, which has a more lustrous appressed sericeous indumentum (Fig. 22A). Further investigation is required to assess whether these forms are of taxonomic significance.
