牛奶子在日文中，又被称作秋茱萸。

Elaeagnus umbellata is known as Japanese silverberry, umbellata oleaster, autumn olive, autumn elaeagnus, or spreading oleaster. The species is indigenous to eastern Asia and ranges from the Himalayas eastwards to Japan. Because it fixes atmospheric nitrogen in its roots, it often grows vigorously and competitively in infertile soils.
