Herbs, perennial, or subshrubs, 0.5-1(-3) m, most parts principally stellate pubescent, also with some simple hairs. Stipules filiform, 4-5 mm; petiole 0.5-3.5 cm; leaf blade ovate to oblong, rarely slightly 3-lobed, 2-6(-7) × 1.2-4(-6) cm, both surfaces stellate pubescent, base acute, obtuse, or truncate to slightly cordate, margin serrate, apex acute to acuminate. Flowers congested into a dense short terminal spike, 1.5-3(-10) × ca. 1 cm, usually only 1 flower open at a time. Epicalyx lobes filiform to lanceolate, acuminate, 8-10 × 1.5-2.5 mm, abaxially hispid with simple or bifurcate hairs and minute stellate hairs, adaxially glabrous. Calyx shallowly cup-shaped, 5-6 mm in diam., accrescent to 6-10 mm in fruit, lobes triangular, ca. 4 × 3 mm, abaxially densely hirsute, adaxially minutely stellate pubescent, apex acuminate. Corolla yellow, 1.3-1.7 cm in diam.; petals obliquely obovate, claw stellate ciliate, apex asymmetrically emarginate. Filament tube 2-3 mm, stellate pubescent. Mericarps (5-)8-15(-18), nearly orbicular, (1-)2-2.5 × 1.5-3(-5) mm in diam., cusps absent, endoglossum usually present, minute. Seeds gray, reniform, 1.2-1.7 mm in diam., glabrous.
Herb or suffrutex, perennial, the stem commonly branched above, up to 3 m high, stellate-tomentellous to stellate-puberulus. Leaves usually long-petiolate, the petiole up to 4 cm long, stellate-tomentellous to stellate-puberulus, the stipules subulate, 4-6 mm long; blade ovate, truncate, rounded or cuneate at the base, ob-tuse to acute at the apex, serrate at the margin, 2-7 cm long and 1.5-4.5 cm wide, stellate-puberulus on both sides, the indumentum however denser on the lower surface, the nervation prominent beneath. Flowers in dense, terminal spikes. these up to 14 cm long, the individual flowers sessile or nearly so; epicalyx bractlets nar-rowly ovate, acute or acuminate, 5-9 mm long and 1-1.3 mm broad, hispid; calyx campanulate, lobed to below the middle, 5-8 mm long, hispid, the lobes ovate, acuminate; petals 7-9 mm long and 3-4 mm wide, the claw barbate; androecium 3-5 mm long, the staminal tube stellate-pilose; styles 5-6 mm long, connate in the lower half. Mericarps 10-15, incurved-rostrate at the apex, 1.5-2 mm long and 0.8-1 mm thick, hispid toward the apex; seeds 1.2-1.5 mm long.
