Suffrutescent bushes, sometimes shrubs or trees, 1-5 m high, densely and strictly branched, strong-scented with a pungent marigold odor; stems slender, arching; bark pale-gray or gray, smooth and glabrous; branchlets slender, densely strigose with short whitish trichomes; principal internodes short or elongate; leaves decussate-opposite, the larger leaves petiolate, the blades subcoriaceous, some-what stiff, dark-green above, paler beneath, broadly elliptic to ovate, sometimes oblong-ovate, 3-6.5 cm long and 1.5-4 cm wide, shortly acuminate to obtuse apically, cuneate-acute or attenuate basally and often contracted-decurrent into the petiole, closely serrate or crenate-serrate along the margins (except basally), roughly scabrous and densely white-punctate with the persistent bulbous bases of the trichomes, often sub-bulate because of the impressed venation, roughly scabrous beneath, the midrib and larger veins prominent, the secondaries ca. 6 per side; petioles slender, 5-14 mm long, strigillose-scabrous. Inflorescences axillary, capitate, 2-6 per node, the heads globose, 8-10 mm wide, scarcely elongate in fruit; peduncles slender, 1-2.5 cm long, usually surpassing the petioles, strigillose-scabrellous; bracts small, chartaceous, green or brown, broadly ovate, acute or subacuminate apically, scabrous or glabrate, to 6 mm long in fruit. Flowers with the calyx compressed, 2-dentate, scarcely more than 1 mm long, densely white-pilosulous; corolla hypocrateriform, white or greenish-white to pale greenish-yellow or yellow, ca. 3 mm long, the tube slender, glabrous, the limb 1.5 mm wide, the lobes broadly rounded, densely puberulent outside and sparsely puberulent inside.
