Stem usually branched, 4.5-22.5 cm tall, glandular pilose. Leaf buds present in axils at proximal nodes. Proximal cauline leaves caducous, less than 1/2 size of median ones, margin entire. Median cauline leaves subelliptic to ovate, 0.5-2 cm × 2.5-10 mm, both surfaces strigose, margin with 3-5 acute lobes toward apex. Flower usually solitary, or cyme 2-4-flowered; pedicel 0.6-2.1 cm, long glandular hairy. Sepals erect or somewhat spreading, ovate, 2.3-4 × 1.4-2.3 mm, glandular or eglandular hairy abaxially, adaxially distally, and marginally, veins 3-8, confluent at apex. Petals yellow, elliptic to broadly so or obovate, 4-7.3 × 2.9-5 mm, 2-16-callose, 3-10-veined, base contracted into a claw 0.6-1.7 mm, apex obtuse. Stamens 3-4.5 mm. Ovary subsuperior, ovoid to broadly so, 1.6-2.2 mm; styles 1.5-1.8 mm. Fl. and fr. Jul-Sep. 2n = 16, 24*.
