Clermontia drepanomorpha, of the Campanulaceae (bellflower) family, is a terrestrial or epiphytic (not rooted in the soil), branching tree 2.5 to 7 m (8.2 to 23 ft) tall. The stalked leaves are 10 to 27 cm (4 to 11 in) long and 1.5 to 4.5 cm (0.6 to 1.8 in) wide. Two to four flowers, each with a stalk 2 to 3.5 cm (0.8 to 1.4 in) long, are positioned at the end of a main flower stalk 5 to 12 cm (2 to 5 in) long. The calyx (fused sepals) and corolla (fused petals) are similar in size and appearance, and each forms a slightly curved, five-lobed tube 4 to 5.5 cm (1.6 to 2.2 in) long and 1.5 to 2 cm (0.6 to 0.8 in) wide which is blackish purple. The berries are orange and 2 to 3 cm (0.8 to 1.2 in) in diameter.
