Description:
Description: Shrub or small tree to ca. 3 m tall; twigs moderately to densely pubescent, with nonchambered pith; buds to ca. 1 mm long, leaves revolute. Leaves coriaceous, oblong or elliptic to slightly ovate, 2.4-6 x 0.7-2.2 cm, base cuneate to rounded, apex acute- to rounded-mucronate, margin entire, plane, adaxial surface sparsely pubescent on midvein, abaxial surface densely pubescent on lamina and midvein with hairs frequently ferruginous, at least when young (with few inconspicuous glandular dots along midvein, these obscured by dense pubescence; petiole 2-6 mm long. Inflorescences axillary racemes to 4-6 cm long; rachis densely pubescent; pedicels 3-7 mm long, sparsely to densely pubescent; bracteoles 2, alternate to subopposite, from nearly basal to near middle of pedicel, narrowly triangular, to ca. 1 mm long; floral bracts to ca. 1.3 mm long. Flowers with triangular calyx lobes, with acuminate apices, 1-2 x 0.7-1.5 mm, abaxial surface moderately to densely pubescent; corolla cylindrical, white, 6-8 x 3-4.5 mm, moderately to densely pubescent; filaments 4-6 mm long; anthers 1.1-1.4 mm long; ovary densely pubescent. Capsules subglobose to short-ovoid, 4.5-6 x 6-7 mm, the placentae subapical; seeds 1.4-3 mm long.
Distribution: Endemic to Brazil (Goiás and Bahia), in sandy or rocky campo, rocky (sandstone) open cerrado, moist woods along streams, at ca. 1000-1600 m alt. Flowering February and March.
Type: Goiás: Chapada dos Veadeiros, 20 km N of Alto Paraíso, 1600 m, 6 Mar 1973, W. R. Anderson et al. 6502 (holotype, UNB, n.v.; isotype, NY).
