It is currently accepted as containing two species; other species previously included in this genus have been transferred to other genera, most of them to Jasminum. They are shrubs or small trees growing to 10 m tall, with flaky bark. The leaves are opposite, simple. The flowers are produced in small clusters of two to seven together. The fruit is a two-parted capsule, with a single seed in each part. The name Nyctanthes means "night flowering".
