The flowers are white and short tubular to bell-shaped, open at night and are up to 4 centimeters long. The flower tube covered with very small scales. The fruits are almost glabrose, pink fruits with persistent, blackening flower remains are broadly ovate in shape and have a diameter of up to 2.5 centimeters. Fruits contain white flesh and do not tear open. The black, rough-warty seeds are oval to pear-shaped. [4]
