Description:
Description: Shrub; twigs sparsely to very sparsely pubescent, with ± nonchambered pith; buds to ca. 1.8 mm long, leaves revolute. Leaves coriaceous, ovate to elliptic, 1-3.1 x 0.6-1.3 cm, base rounded to slightly cordate, apex acute- to rounded-mucronate, margin entire (slightly sinuous), plane to slightly revolute, both surfaces glabrous to sparsely pubescent on midvein, abaxially often with few to several inconspicuous glandular dots along midvein; petiole 1-2.5 mm long. Inflorescences axillary racemes to 5-10 cm long; rachis sparsely to moderately pubescent; pedicels 3.5-7 mm long, sparsely to moderately pubescent; bracteoles 2, at or near base to within lower 1/3 of pedicel, narrowly triangular, to ca. 1.1 mm long; floral bracts to 1.5 mm long. Flowers with triangular calyx lobes, with acuminate apices, 1-1.5 x 0.9-1.5 mm, abaxial surface glabrous to very sparsely pubescent, especially near base; corolla cylindrical to urceolate-cylindrical, white, 6-7.5 x 3-3.5 mm, glabrous; filaments ca. 3.5 mm long; anthers ca. 1.3 mm long; ovary glabrous to very sparsely pubescent near apex. Capsules subglobose to short-ovoid, 4-5 x 5.5-6.5 mm, placentae subapical; seeds not seen.
Distribution: Endemic to Chachapoyas region of N Peru, at ca. 2700 m alt.
Type: Peru Amazonas: Chachapoyas, Mathews s.n. (holotype, G, n.v.; frag. and photo of holotype, F; isotypes, E, K, S).
