Datura wrightii is a large, horizontally spreading plant with large dentate or lobed leaves and nearly equally large white flowers. The fruit is densely spiny. There are two carpels with axile placentation, but the capsule has 4 locules by virtue of the formation of a false septum. Each locule has many ovules. Datura wrightii is found at lower and middle elevations in dry sandy soil.
