Leaves with petioles 5–9 × +1–1.2 mm +, semiterete, adaxially plane; blades narrowly elliptic or ovate-elliptic, 55–90 × +24–40 mm +, 2.2–2.5 times longer than wide, concolorous or slightly discolorous when dry, dull green or dull light brown adaxially and lighter abaxially, with simple grey trichomes +0.1–0.2 mm +scattered along the midvein on both faces; base obtuse or widely cuneate, sometimes abruptly cuneate at the insertion with the petiole; apex acuminate in +5–7 mm +and with a perceptible mucron +0.5–0.7 mm +; glandular dots 4 to 8 / mm², visible when backlit and occasionally perceptible on the surfaces, smaller than +0.1 mm +in diameter; midvein impressed adaxially or sometimes plane along its distal portion (sometimes it may appear to be raised due to the presence of trichomes), raised abaxially; lateral veins 10-12 at each side, finely raised and scarcely perceptible on both faces, leaving the midvein at angles about 60°; secondary lateral veins and higher order venation scarcely or not at all perceptible; intramarginal vein +0.8– 1 mm +from the revolute margin. Inflorescences ramiflorous or axillary, with up to ten flowers densely crowded in glomerules with glabrous axes to 1 × +1 mm +, with 3 to 4 series of bracts proximally, these elliptic or rounded, carenate, slightly increasing in size distally, the most basal ones to 0.5 × +0.8 mm +, the most distal ones to 1.8 × +1 mm +, glabrous or with sparse trichomes to +0.1 mm +; bracts subtending the flowers elliptic, 1.5–2 × +1.5 mm +; flowers sessile; bracteoles elliptic or ovate, separate, carenate, about the same size of the bracts and glabrous or with sparse trichomes as them; flower buds globose or obovate, 4–5 × +4 mm +, pilose on the ovary, the trichomes simple, white, to +0.1 mm +, usually not concealing its surface; sepals four, distinct, ovate or hemispheric, 1–1.8 × +1.5–1.8 mm +, lighter than the rest of the bud when dry, glabrous or with cilia to +0.1 mm +; petals four, rounded, +2.5–3 mm +in diameter; stamens to +4 mm +, the anthers elliptic, 0.6–0.7 × +0.4 mm +, eglandular; calyx tube to +0.2 mm +deep, glabrous; style to +5 mm +, glabrous, the stigma punctiform; ovary with two locules and 2 ovules per locule.
