Subshrubs 0.5-2.5 m tall, much branched, isophyllous. Stems 4-angled, bifariously whitish pubescent, sometimes glabrescent. Petiole 2-4 cm, whitish pubescent; leaf blade ovate, elliptic, or elliptic-ovate, 3-11 × 2-5 cm, abaxially pale green and sparsely pubescent, adaxially dark green and pubescent, cystoliths abundant on both surfaces, secondary veins 4-7 on each side of midvein, base narrowly cuneate and decurrent onto petiole, margin crenate-serrate, apex acuminate and sometimes falcate. Inflorescences axillary or terminal, subcapitate spikes, rarely reduced to a single flower; peduncle 0-4 mm, densely white pubescent; bracts persistent, hirsute; outermost sterile bracts leaflike, petiolate, lanceolate to ovate-lanceolate, 1.5-2.5 × 0.3-0.4 cm; inner floral bracts linear-oblong, 1.2-1.6 cm, with 1 reddish brown vein; bracteoles linear to oblanceolate, ca. 10 × 2 mm, pilose, apex obtuse.
