Herbs, annual or perennial; hemiparasitic, caudex knotted. Stems erect, not fleshy, glabrous, sparsely to densely puberulent, densely villous, or glandular-pubescent. Leaves basal and cauline, opposite; petiole present; blade leathery, not fleshy, margins entire, pinnatifid, or 2-pinnatifid. Inflorescences terminal, loose racemes; bracts present. Pedicels present; bracteoles absent. Flowers: sepals 5, calyx radially symmetric, campanulate or turbinate, lobes linear to deltate, sometimes lanceolate; petals 5, corolla yellow, bilabiate, campanulate, abaxial lobes 3, adaxial 2; stamens 4, didynamous, filaments glabrous or ciliate, anthers villous; staminode 0; ovary 2-locular, placentation axile; stigma truncate. Capsules: dehiscence loculicidal. Seeds 300–500, brown to blackish, ovoid to deltoid, wings present (absent in A. pedicularia). x = 14.

Species 8 (7 in the flora).

Molecular phylogenetic analysis supports a close relationship of Aureolaria with Agalinis, Esterhazya J. C. Mikan, and Seymeria (J. R. Bennett and S. Mathews 2006). Further evidence for these relationships is similarities in floral morphology among these genera.

Aureolaria greggii (S. Watson) Pennell occurs broadly throughout northern Mexico.
