Perennial, spreading, glandular-pubescent, viscid, branched herb, 30–50 cm tall, with many stems that are erect or decumbent and branched from the base. Leaves are small and closely spaced along the branches; lower leaves are long-petiolate, deltoid-ovate to cordate or hastate, about 25 mm long and 4–6 mm wide, while upper leaves are gradually reduced, with shorter petioles or becoming subsessile and narrower, ovate to lanceolate. Calyx lobes are lanceolate, about 4 mm long, with white, scarious margins, and are densely spreading-glandular hairy. Corolla is yellow, densely glandular-pubescent, up to 8 mm long, with a whitish tube. Spur is curved and as long as or longer than the corolla. Flowers have two pairs of unequal-length, included stamens. Fruits are globose to ovoid capsules containing tuberculate-verrucose seeds.
