Shrubs 30–60 cm tall, stems decumbent, virgately branched, with two subequal lateral branches developing adjacent to inflorescence; leafy stems 0.8–1.5 mm in diam., terete, brown, moderately shortly strigillose-canescent with white ascendant trichomes 0.1–0.2 mm long; older stems with peeling brown bark. Leaves opposite, blade elliptic to broadly elliptic or obovate-elliptic, 0.8–1.8 × 0.3–1.0 cm, apex obtuse to rounded, or occasionally truncate, usually apiculate, base acutely cuneate, sides slightly attenuate and decurrent, subcoriaceous to coriaceous and brown when dry, bright green when fresh, both surfaces moderately shortly strigillose with appressed trichomes 0.1–0.2 mm, pustular, venation obscure, 1–2 (–3) pairs secondary veins arising near base, petiole 2–4 mm long, 0.4–0.5 mm in diam., shortly strigillose. Inflorescences terminal, scorpioid-cymose, forked 1(–2) times, axes densely shortly strigillose-canescent like the stems, 2–4 cm long, peduncle 0.5–0.8 cm long, primary axes 1.5–3 cm long. Flowers sessile to subsessile, 18–23 per axis, calyx lobes 5, unequal, 1–2 larger, ovate, 1–1.5 × 0.6–1 mm, 3–4 smaller, narrowly ovate to oblong, 1 × 0.3–0.4 mm, densely strigillose toward base, corolla shortly funnelform, 2 mm long, tube 1-1.5 mm long, externally densely villose-strigillose, internally slightly villosulous in throat, lobes 5, subcircular, 0.5–0.7 × 0.5–0.7 mm, margin crisped, stamens 5, attached midway in tube, basifixed, anthers ellipsoid, 0.5–0.6 mm long, apiculate; ovary cylindric-ovoid, glabrous except for ring of trichomes 0.2–0.3 mm long surrounding base of style, style terminal, 0.3 mm long, stigmatic column 0.3–0.4 mm long, cylindrical-conical, apex strigillose, base annular. Fruit broadly ovoid, 1 × 1.6 mm, shortly strigillose, shallowly 4-lobed, dry, splitting into 4 wedge-shaped nutlets. Nutlets 1.3–1.5 × 1–1.1 mm, dorsally strigillose, ventrally glabrous, brown.
