Description:
Description: Subshrub to ca. 0.5 m tall, with bark not well developed; twigs ± glabrous to densely pubescent, with nonchambered to irregularly chambered pith; buds to ca. 1 mm long, leaves conduplicate. Leaves coriaceous, linear and ± curved, 1.2-3.5(-4) x 0.2-0.5 cm but appearing narrower because lamina strongly adaxially folded, thus obscuring adaxial surface, base narrowly cuneate, apex narrowly acute to short-acuminate, margin entire, to serrulate in juvenile leaves due to presence of gland-headed hairs, plane, adaxial surface sparsely pubescent, abaxial surface with or without gland-headed hairs, otherwise glabrous to very sparsely pubescent on basal portion of midvein, lacking or with few inconspicuous glandular dots along midvein; petiole 2-6.5 mm long, not flexuous. Inflorescences axillary racemes to 0.3-1.5 cm long; rachis very slightly to densely pubescent; pedicels 2-7.5 mm long, glabrous to densely pubescent; bracteoles 2, subopposite to alternate, from nearly basal to near midpoint of pedicel, narrowly triangular, to ca. 1 mm long; floral bracts to ca. 1 mm long. Flowers with triangular calyx lobes, with acuminate apices, 1-1.5 x 0.6-1 mm, abaxial surface essentially glabrous; corolla cylindrical, white, 7-9.5 x 2.5-4.5 mm, glabrous; filaments 4.5-5.5 mm long; anthers 1.1-1.3 mm long; ovary glabrous to moderately pubescent, placentae ± subapical(?). Capsules not seen.
Distribution: Endemic to SE Brazil (Minas Gerais), in open sandy or rocky areas, at 1300-1400 m alt. Flowering October to December.
Type: Brazil. Minas Gerais: Serra do Cipó, km 137 da Estrada de Conceiçao, 1300 m, 6 Dec 1949, Duarte 2103 (holotype, RB, n.v.; isotypes, L, LIL, n.v.).
