Flowers Fragrant, white flowers have a yellow throat and are shaped like pinwheels (1.8 - 3.1 cm long, 2 cm wide). Salverform flowers have 5 bean-shaped lobes with thin, hook-like tips. Floral buds are rounded. The inflorescence is known as a cyme.
Fruits Dry, dehiscent fruits are known as follicles. Ellipsoid follicles may be sharply pointed or rounded on the ends (2 - 4.5 cm long, 0.6 - 3 cm wide).
Habitat Occurs in tropical mixed forests and brushwoods at altitudes of 500 - 1700 m. It is native to Singapore, but considered an endangered species.
Cultivation This species flowers best in full sun, but it also tolerates light shade. It should be planted in fertile, well-drained soil that is kept moist. Apply mulch near the base of the plant to conserve soil moisture. The branch tips should be pruned to encourage bushy growth. 
Etymology Genus Tabernaemontana is named after Jakob Theodor von Bergzaben (1520 - 1590) (Latinised surname Tabernaemontanus meaning "tavern in the mountain"), who was a German herbalist. Species corymbosa means with flowers arranged in corymbs.
Ethnobotanical Uses Medicinal ( In China, the barks and leaves are thought to help fractures heal.)
