Tetraena is a possible genus of flowering plants in the family Zygophyllaceae, subfamily Zygophylloideae.
The flower is usually tube-like in appearance with white to pale orange petals.
The ripe fruit is variable in shape, splitting into parts before releasing the seeds.
Molecular phylogenetic studies suggested that the genus Zygophyllum was not monophyletic, since Tetraena and some other genera were nested within it.
