Cyanea gibsonii. a member of the Campanulaceae (bellflower) family. is a palm-like tree 1 to 7 m (3.2 to 23 ft) tall. The leaves are elliptic or oblong, about 20 to 80 cm (8 to 31 in) long and 6.5 to 20 cm (2.5 to 8 in) wide; the upper surface usually is smooth, while the lower is covered with fine hairs. The leaf stem often is covered with small prickles throughout its length. The inflorescences are horizontal and clustered among the leaves, each bearing 5 to 15 curved flowers that are blackish-purple externally and white or pale lilac within. The fruit is a yellowish-orange berry about 1.5 to 3 cm (0.6 to 1.2 in) long. In 2016, the Service recognized the change in taxonomy from Cyanea macrostegia ssp. gibsonii to the full species C. gibsonii.
