The '''Datiscaceae''' are a family of [dicotyledon](/source/dicotyledon)ous plants, containing two species of the genus '''''Datisca'''''. Two other genera, ''[Octomeles](/source/Octomeles)'' and ''[Tetrameles](/source/Tetrameles)'', are now classified in the family [Tetramelaceae](/source/Tetramelaceae).
Datiscaceae are large herbaceous plants, with alternate and pinnate leaves.
They are [actinorhizal plant](/source/actinorhizal_plant)s, that host [nitrogen-fixing bacteria](/source/nitrogen-fixing_bacteria) in their roots, and are the only ones that are non-woody, although non-actinorrhizal plants also fix nitrogen, such as the [legume](/source/legume)s.

The genus ''Datisca'' contains two or three species;[{{cite journal |author1=Christenhusz, M. J. M. |author2=Byng, J.

The species ''[Datisca cannabina](/source/Datisca_cannabina)'' is found in Crete and Turkey, and closely related ''[Datisca nepalensis](/source/Datisca_nepalensis)'' is found in the [Himalayas](/source/Himalayas), and is sometimes included in ''D. cannabina''. It grows to about 2.0 m tall, and in May to August it produces small greenish-yellow flowers. This species is strictly [dioecious](/source/dioecious), with male and female flowers on different plants. It is grown for ornamental foliage and can be used to produce a [laxative](/source/laxative) and a yellow dye.[{{cite web | url = http://www.efloras.org/florataxon.aspx?flora_id=110&taxon_id=220003876 | work = Nepal Checklist | title = Datisca cannabina L. | access-date = 2007-12-16 }}][{{cite web | url = http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=220003876 | work = Flora of Pakistan | title = Datisca cannabina | access-date = 2007-12-16 }}][{{cite encyclopedia | url = http://www.britannica.com/eb/topic-152267/Datisca-cannabina | title = Datisca cannabina (plant) | encyclopedia = Encyclopædia Britannica online | access-date = 2007-12-16 }}]
The North American species ''[Datisca glomerata](/source/Datisca_glomerata)'' is native to California, Nevada, and Mexico.[{{cite web | url = https://plants.usda.gov/java/profile?symbol=DAGL2 | work = PLANTS | title = Datisca glomerata (K.
