Shrubs to 3 m tall; bark of main bole unknown. Vegetative and reproductive parts (where indicated) bearing a moderately dense, shortish indumentum, the individual trichomes dibrachiate or not, appressed to somewhat reflexed (appearing villous), frequently irregularly contorted, whitish or reddish. Branchlets laterally compressed but becoming rounded, smooth, moderately short villous (hairs mostly reflexed and not dibrachiate) becoming glabrous, oil glands common and prominent (after indumentum falls away). Leaves opposite, mostly occurring in 2–4 pairs along seasonal growth of branchlet, thinly coriaceous, venation brochidodromous (invisible to obscure), discolorous, somewhat glossy above but matte below. Axillary colleters absent. Petioles 1.7–2.5 mm long, broadly sulcate above, moderately hairy towards base adaxially in sulcus. Leaf blades 0.9–2.0 (–2.7) × 0.6–0.9 cm, narrowly elliptic or elliptic to narrowly obovate, base cuneate, surface flat to slightly and irregularly (but broadly) sinuous on drying, margin flat or drying slightly revolute, apex obtuse; abaxial surface glabrescent, oil glands common (use magnification) and drying brownish and slightly sunken, midvein flush and becoming imperceptible towards apex; abaxial surface sparsely glabrescent, oil glands relatively sparse to moderate and somewhat less prominent than adaxially, secondary veins few and barely perceptible, the secondaries connected at their ends by a slightly arching pseudo-intramarginal vein 0.3–0.8 mm from leaf margin (i.e., lacking an intramarginal vein distinct from pseudo-intramarginal vein). Inflorescence a monad; the base of the flowering branchlets each with (2–)4–6 flowers arising alternately, each flower subtended by a short, hairy and somewhat ovate to broadly triangular caducous bract. Pedicels (5–)10–15(–20) mm long, 0.3–0.5 mm wide, round in transverse section, stiff, ascending, sparsely hairy (especially near base) to nearly glabrous, moderately glandular throughout, anthopodium present or absent. Bracteoles 2, linear, 1.0–1.2 × 0.3–0.5 mm, sparsely hairy. Hypanthium cupulate 2.0–2.5 mm long, 1.4–1.8 mm wide at base of calyx lobes, densely short-hairy, oil glands absent or sparse (and obscured by hairs); ovary apex glabrous. Calyx lobes 4, 1.5–1.9 mm, broadly ovate to rounded, glabrous on both faces apart from sparse apical hairs (white or reddish), strongly reflexed in athesis. Petals 4 (material scant), ca. 2.5 mm × 2 mm, obovate to widely obovate, glabrous on both faces apart from sparse apical hairs (contorted irregularly), oil glands absent. Staminal region (i.e., lacking a well-defined staminal ring) 1.6–1.8 mm diameter in anthesis, sparsely hairy (trichomes simple); stamens 35–45; filaments 1.5–2.5 mm; anther sacs 0.5–0.7 mm long, globose, basifixed, eglandular. Style 2.5–2.8 mm, glabrous or sparsely hairy basally; stigma narrow and only slightly capitate. Fruit unknown.
