Duboisia (commonly called corkwood tree)[citation needed] is a genus of small perennial shrubs and trees that grow up to 14 metres (46 feet) tall, with extremely light wood and a thick corky bark.

The inflorescence is an open cymose panicle of apically small white flowers, sometimes with a purple or mauve striped tube.

Aboriginal Australians sometimes chew the nicotine-containing leaves of Duboisia hopwoodii (see entry on pituri) mixed with wood ash for their stimulant and, after extended use, depressant effects.

A derivative of scopolamine is the drug butylscopolamine, a potent peripherally acting antispasmodic.

The genus was named by Robert Brown in honour of Louis DuBois who wrote Méthode éprouvée, avec laquelle on peut parvenir facilement et sans maître à connaître les plantes de l'intérieur de la France et en particulier celles des environs d'Orléans, par M. Dubois, théologal de l'église d'Orléans, ancien démonstrateur du Jardin des plantes (1803).
