It has the traditional name Situla, a Latin word meaning "bucket" or "water jar". In Chinese, X Liáng, meaning Temple, refers to an asterism consisting of Aquarii, 44 Aquarii, 51 Aquarii and HD 216718. Consequently, Aquarii itself is known as the Third Star of Temple. From this Chinese name, the name Heu Leang was appeared, meaning the Empty Bridge.
