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[1].
Specifically for A. flava, the plant is perennial and parasitic on Quercus alba (white oaks). The stem are glabrous and grow to approximately 2 or more meters. The leaves are lanceolate or elliptic lanceolate, the upper portion is usually entire or serrate, the lower portion is usually pinnately lobed to parted, glabrous or glabrate, and grows to approximately 7-17 cm long and 1.5-7 cm wide. The inflorescences, the pedicels are glabrous, are 4-25 mm long at the anthesis, curving upward. The calyx lobes are lanceolate to triangular, equaling or slightly longer than the tubes which are entire, and are 3-5 mm long. The corolla is 3-5 cm long. The capsules are glabrous. Flowers from August to September; and September to October[1].
