Cyanea procera, a member of the Campanulaceae (bellflower) family, is a palm-like tree 3 to 9 m (10 to 30 ft) tall with stalkless, lance-shaped leaves 60 to 75 cm (24 to 30 in) long and 10 to 17 cm (3.9 to 6.7 in) wide with tiny hardened teeth along the margins. Each flower cluster has a stalk 25 to 40 mm (1 to 1.6 in) long and comprises 10 to 20 flowers, each on a stalk 6 to 10 mm (0.2 to 0.4 in) long. Each flower has a hypanthium, 15 to 20 mm (0.6 to 0.8 in) in length and 7.6 to 13 mm (0.3 to 0.5 in) in width, topped by shallow triangular calyx lobes 3 to 4 mm (0.1 to 0.2 in) long and about 4 to 5 mm (0.2 in) wide. The purplish corolla forms a nearly upright or slightly curved tube 6 to 8 cm (2.4 to 3.1 in) long and 6 to 11 mm (0.2 to 0.4 in) wide, which ends in five downwardly curving lobes which make the flower appear one-lipped. The ellipse- or egg-shaped berries are 3 to 4.5 cm (1.2 to 1.8 in) long and 2 to 2.8 cm (0.8 to 1.1 in) wide.
