  • Description

    Description: Shrub to ca. 2 m tall; twigs with or without gland-headed hairs, otherwise glabrous, with non-chambered pith; buds to ca. 1 mm long, leaves conduplicate. Leaves coriaceous, linear and curved, to narrowly ovate in juvenile leaves, (1.7-)3-9 x 0.1-0.5 cm, but appearing narrower because entire 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 the presence of gland-headed hairs, plane, adaxial surface glabrous, abaxial surface with or without gland-headed hairs, otherwise glabrous, lacking or with few inconspicuous glandular dots along midvein; petiole 5.5-15(-20) mm long, slender, often flexuous. Inflorescences axillary racemes, or terminal racemes or panicles, to 2-6 cm long; rachis glabrous; pedicels 4.5-14 mm long, glabrous (very slightly pubescent); bracteoles 2, alternate to opposite, from nearly basal to within lower 1/4 of pedicel, narrowly triangular to linear, to ca. 1 mm long; floral bracts to ca. 3 mm long, grading into leaves. Flowers with triangular calyx lobes, with acuminate apices, 1-1.5 x 0.5-1.1 mm, abaxial surface glabrous; corolla cylindrical, white or cream, 6.5-10.5 x 2.5-3.5 mm, glabrous; filaments 4-5 mm long; anthers 1-1.7 mm long; ovary glabrous. Capsules short-ovoid to subglobose, 3.5-5.5 x 5-7 mm, placentae subapical to nearly central; seeds 1.5-2.9 mm long.

    Distribution: Endemic to SE Brazil (Minas Gerais), in cerrado vegetation, moist rocky areas, at ca. 1200-1400 m alt. Flowering November.
