description

Nyctanthes arbor-tristis grows as a deciduous shrub or as a smaller tree to usually around 10 meters high.

The simple, short-stalked and leathery leaves are opposite. The petiole is up to 10 millimeters long. The leaves are rough, scaly, slightly short-haired on the top and slightly hairy on the underside, are ovate, have entire margins or have individual teeth and are pointed to pointed. They are 6–12 inches long and 6–8 inches wide. The leaf base is rounded to slightly heart-shaped or truncated. The stipules are missing.

The flowers appear axillary or terminal in few-flowered and stalked cymes with bracts in thyrsigen inflorescences. The strongly fragrant, orange-white and salver-shaped, short-stalked, hermaphrodite flowers are double- coated . The flowers are heterostyle . The cup-shaped and trimmed to weakly 5-9 lobed, lobed, externally hairy calyx is about 5–6 millimeters long. The solid orange corolla tube is cylindrical and about as long as the 5–9 sweeping, up to 15 millimeters long, roof-top and more or less spirally twisted, white lobes. The almost seated only 2 stamens are located above in the corolla tube. The two-chamber ovary is upper constant with a more or less long pen with slightly zweilappiger scar . The flowers open at night and the crowns are usually shed at sunrise.

Flat, up to about 2 centimeters in size, upside-down heart-shaped to rounded and two-seeded, split fruits with calyx remains are formed. They divide in the middle in the transverse direction into non-opening partial fruits.

The number of chromosomes is 2n = 44.
