Small shrub from a thick woody taproot with the base reaching 7 mm in diameter, not appearing rhizomatous, much-branched from base, to 5 –8 dm tall. Young stems moderately pubescent with two-celled unbranched hairs, these geniculate between first and second cells and pointing apically; older stems glabrescent. Sympodia appearing unifoliate but the structure is difficult to evaluate. Leaf blades 1.5 –2.5 + 0.5– 1 cm, linear to elliptic, chartaceous to membranaceous, nearly glabrous to moderately pubescent adaxially and abaxially with 1– 2-celled unbranched hairs, these lying flat along blade; base acute, often decurrent into petiole; apex acute; petioles absent to 4 mm, moderately pubescent. Inflorescences with 1–3 flowers, the axes sparsely to moderately pubescent with unbranched hairs; peduncle absent or nearly so; rachis absent; pedicels 5–10 mm in flower, 10– 20 mm in fruit. Flowers with the calyx 2–4 mm long, the tube 1–2 mm, the lobes 2–3+ 0.5–1 mm, linear-lanceolate, moderately pubescent; fruiting calyx 5 –8 mm in length. Corolla 8–12 mm in diameter, rotate with abundant interpetalar tissue, membranaceous, the tube 1.5–2.5 mm, the lobes 1.5–2.5+ 0.8–1.5 mm, triangular, acute at apices, moderately pubescent abaxially with hairs like those of the leaves, glabrous adaxially. Stamens 1.5–2 mm; filaments ca. 0.5 mm; anthers 1.5–2+ 0.5–1 mm, oblong, the base cordate. Ovary glabrous; style 2.5–3 + 0.2–0.4 mm, exserted beyond stamens; stigma to 0.5 mm wide. Berries 5– 12 mm in diameter, globose, white to brown when dried, glabrous, appearing to be explosively dehiscent due to the presence of small tears and the wrinkled, deflated appearance of the dried fruits. Seeds 5–15 per fruit, ca. 2.5+ 1.5 mm, with a small notch where connected to placenta, the margin not swollen, the surface with fine raised ridges radiating from center to edges and shallow ridges running parallel to margin.
