The orchid genus described by Karsten as Duboisia is now included in Myoxanthus. For the prehistoric antelope genus, see ''Duboisia (antelope).

The alternate, glabrous leaves are narrow and elliptical. The inflorescence is an open cymose panicle of apically small white flowers, sometimes with a purple or mauve striped tube. They flower profusely in spring. The fruit is a small, globular, black, juicy berry.

The leaves of Duboisia leichhardtii and Duboisia myoporoides contain the pharmaceutically important ingredients scopolamine and hyoscyamine and some other accompanying minor alkaloids. A derivative of scopolamine is the main active ingredient of the drug butylscopolamine, a potent antispasmodic and analgesic. These trees are commercially grown for the pharmaceutical industry.

Indigenous Australian pituri preparation

List of plant species used to make ashes for Indigenous Australian pituri preparation:

• Acacia aneura
• Acacia calcicola
• Acacia coriacea
• Acacia eutrophiolata
• Acacia ligulata
• Acacia pruinocarpa
• Acacia beauverdiana
• Acacia salicina
• Casuarina decaisneana
• Eucalyptus coolabah
• Grevillea stenobotrya
• Grevillea striata
• Senna artemisioides helmsii
• Ventilago viminalis
• Hakea species

There is not much information regarding what if any psychoactive alkaloids might be present in the ash itself, since combustion tends to destroy or evaporate away alkaloids. The ash is said to be an important component in pituri preparation.

Duboisia arenitensis is a new Australian species, described in 1995.
