description

Cestrum aurantiacum is a 1.5 to 6.5 m high shrub or occasionally a tree that grows up to 8.5 m high . The twigs are hairless or sparsely tomentose. The leaves are egg-shaped to elliptical, 7 to 17 cm long and 2.5 to 5.5 cm wide. Both leaf sides are hairless, the tip is pointed or tapered to a short point, the base is pointed to blunt or occasionally briefly tapered. The leaf stalks are 1 to 3 cm long and hairless.

The terminal or axillary, umbellate or racemose inflorescences consist of a few to a few flowers . The inflorescence axis is finely hairy or hairless, the bracts linear and later sloping. The flowers are sessile, almost sessile, or stand on peduncles up to 1.5 mm long. The calyx is tubular, 5 to 6.5 (rarely up to 9) mm long and hairless except for the (0.7) 1 to 2 (3) mm long, ciliate calyx tips. These are awl-shaped and long-prickly or rounded and long-prickly and run down the calyx as five nerve tracts. The orange or rarely yellow crown has a 17.5 to 20 mm long corolla tube, the corolla lobes are 3 to 3.5 (5.5) mm long, egg-shaped or lanceolate. At the edge they are papillos- hairy on the outside . The stamens are 4 to 6.5 mm long, swollen and bent knee-shaped, trough-like or almost like an appendage. The base and the vascular bundles of the stamens are hairy. The stylus is 16.5 to 18.5 mm long.

As fruits, they form white, 8 to 12 mm long berries with seven to nine seeds that are about 3 to 5 mm long.

The number of chromosomes is 2n = 16.
