Zygophyllaceæ

Zygophyllaceæ, a natural order containing about a hundred species of herbaceous plants, shrubs, and trees, chiefly natives of subtropical countries. The most important genus is Guaiaecum (q.v.). The abundance of species of Zygophyllum and some other genera constitutes a most striking feature of North African and Arabian deserts. The flowers of Z. fabago are employed as a substitute for capers, under the name of Bean-capers.
