Description
In the genus Aureolaria, the plants are either annual or perennial. They are parasitic on the roots of Quercus (oaks) and they turn black when dried. The cauline leaves are opposite or subopposite. The flowers are showy, the calyx is 5-parted, the lobes are shorter to longer than the tube. The corolla is yellow in color, bilabiate, and 5-parted. The tube is campanulate and the lobes are spreading. There are 4 stamens, didynamous, included, filaments are flattened, and the 2 longer more or less lanose. The anther sacs are basally awned. The stigma is capitate and exserted (Radford 1964).
Specifically for A. virginica, they’re perennial parasitic plants of the white oak group. The stems are pubescent, weakly branched or unbranched altogether, and grow to approximately 1 m or more tall. The leaves are lanceolate or ovate-lanceolate, entire or coarsely sinuate to pinnately lobed or parted, puberulent, or weakly tomentose, and most are 6-12 cm long, 1.5-4.5 cm wide. The terminal raceme has distinct, flowers that are solitary in the axils of opposite bracts. The pedicels are glabrous and most of the time less than 3 mm long at the anthesis. The calyx lobes are lanceolate, equaling or much longer than the tube, approximately 3-10 mm long, and is entire. The corolla is 3.5-4.5 cm long. The capsule is broadly ovoid, 1-1.5 mm long, are pubescent. The pedicels are 6 mm long. The seeds have several irregular, narrow, hyaline wings. Flowers from May to July; then August to September (Radford 1964).
