Tetraena
From Wikipedia, the free encyclopedia
Tetraena is a possible genus of flowering plants in the family Zygophyllaceae, subfamily Zygophylloideae. As of January 2025[update], Plants of the World Online and the World Flora Online accepted it as a synonym of Zygophyllum.[1][2]
Species formerly placed in Tetraena are shrubby or herbaceous, the tallest being around 1.5 m (4.9 ft). The leaves are opposite, or sometimes borne on short shoots and then appearing to be alternate. They may or may not have stalks (petioles). The flower usually has five petals and five sepals, rarely four, and ten stamens. The flower is usually tube-like in appearance with white to pale orange petals. The ovary has three to five chambers (locules). The ripe fruit is variable in shape, splitting into parts before releasing the seeds.[3]
