Description:
Description: Shrub to small tree to 5 m tall with longitudinally furrowed bark; twigs nearly glabrous to miderately pubescent, with nonchambered to clearly chambered pith; buds to ca. 1 m long, leaves revolute. Leaves coriaceous, ovate to elliptic or oblong, 0.6-5.7 x 0.3-1.7(-1.9) cm, base cuneate to rounded (very slighlty cordate), apex acuminate or acute- to retuse-mucronate, margin entire, plane to revolute, adaxial surface glabrous, but sparsely pubescent on midvein, abaxial surface glabrous (very sparsely pubescent along basal portion of midvein), usually with few very inconspicuous glandular dots along midvein; petiole 1.5-8 mm long. Inflorescences axillary racemes to 1-3.5(-4.5) cm long; rachis moderately to densely pubescent; bracteoles 2, alternate to opposite, from nearly basal to near midpoint of pedicel, triangular to linear, to ca. 1.5 mm long; floral bracts to ca. 1.7 mm long. Flowers with triangular calyx lobes, with acuminate apices, 0.8-2.7 x 0.6-1.8 mm, abaxial surface glabrous to moderately pubescent; corolla cylindrical, white, 5-8 x 2-4 mm, glabrous; filaments 4-5 mm long; anthers 0.9-1.5 mm long; ovary glabrous to sparsely pubescent (with few hairs at apex and around base). Capsules short-ovoid to subglobose, 4.5-7 x 5.5-10 mm, very thick walled, placentae subapical; seeds 1.5-3.2 mm long.
Distribution: Endemic to SE Brazil (from Paraná south to Rio Grande do Sul in the Serra do Mar), in various habitats, at 350-2000 m alt.
