Annual herb, to ± 15(–30) cm tall; erect or decumbent; young stems pubescent with sessile, stellate, and tufted hairs, becoming sparsely pubescent in age with predominantly sessile-stellate hairs with appressed arms. Leaves broadly ovate to obovate, 0.9–6.2 cm long, 0.5–4.2 cm wide, apex retuse to rounded, mucronate, margin serrate to crenate, base cordate to truncate, slightly discolorous, paler below, pubescent above with mostly sessile-stellate hairs, and below with sessile-stellate hairs; palmately (3–)5-nerved from the base; petiole 0.3–4 cm long, stellate-pubescent; stipules filiform to subulate, (1–)2–8 mm long, reddish brown when dry with very few scattered stellate, bifurcate, and simple hairs, caducous. Inflorescences 2–3-flowered cymes or flowers solitary; peduncle (0.3–)0.5–3 cm long, ± 0.5 mm wide; pedicels 2–10 mm long; peduncle and pedicels stellate pubescent; epicalyx bracts reddish, broadly ovate to cordiform, (2–)4–8 mm long, (1–)2–6(–8) mm wide (in flower), slightly accrescent, (3–)6–13 mm long, (1.5–)4–10 mm wide (in fruit), apex acute or slightly acuminate, base cordate or rarely cuneate, subsessile to short stipitate, sparsely stellate-pubescent. Floral buds obscured by the epicalyx bracts. Sepals narrowly-lanceolate to lanceolate, (2.5–)4–10 mm long, 1–2.5 mm wide, accrescent in fruit, stellate pubescent without, glabrous within. Petals broadly obovate, asymmetrical, ± (2.5–)8 mm long, (1–)3–4(–5.5) mm wide, yellow, glabrous. Staminal tube 0.5–2 mm long, free portion of filaments ± 1 mm long, anthers ± 1 mm long, free portion of staminodes 2.5–5 mm long, glabrous. Ovary globose, 1–2 mm long, 1–2 mm in diameter, densely velutinous; 4 ovules per locule; style 2–4 mm long, glabrous; stigma lobes 1–1.5 mm long, spreading. Capsules subglobose to ovoid-oblong, somewhat flattened at the apex, 4–8 mm long, 3–5 mm in diameter, stellate pubescent, 2–4 seeds per locule; seed ovoid-trigonous to turbinate, 1.5–2.3 mm long, 1–1.5 mm wide, densely tuberculate, with a grey surface and a small, smooth, and darker-colored apical process, elaiosome not present.
