The Zygophyllaceae is a family of flowering plants that contains the bean-caper and caltrop. It includes around 285 species in 22 genera.
In the APG III system of classification, the families Zygophyllaceae and Krameriaceae compose the order Zygophyllales. In the previous version of their classification system, the Angiosperm Phylogeny Group had included the option of placing Krameria within Zygophyllaceae.
Zygophyllaceae is divided into five subfamilies. A molecular phylogeny of the family was published in 2000. Phylogenies of groups within the family have also been published. A phylogeny of the southern African species of Zygophyllum was published in 2008.
Peganum was in Zygophyllaceae before being moved to the newly created family Nitrariaceae.
King Clone, a Creosote bush (Larrea tridentata) in California, is believed to be the oldest living organism.
Balanites is a genus of flowering plants in the caltrop family, Zygophyllaceae. [more]
Bulnesia
Bulnesia is a genus of flowering plants in the caltrop family, Zygophyllaceae. The wood of some ? particularly B. arborea and B. sarmientoi ? is traded as verawood (colloquially "vera") or "lignum vitae". They are close relatives of the "true" lignum vitae trees of genus Guaiacum. [more]
Guaiacum, sometimes spelled Guajacum, is a genus of flowering plants in the caltrop family Zygophyllaceae. It contains five species of slow-growing shrubs and trees, reaching a height of approximately 20 m (66 ft) but are usually less than half of that. All are native to subtropical and tropical regions of the Americas and are commonly known as lignum-vitae, guayac?n (Spanish), or ga?ac (French). The genus name originated in Maipurean, the language spoken by the native Ta?nos of the Bahamas; it was adopted by English in 1533, the first word in that language of American origin. [more]

Kallstroemia is a genus of flowering plants in the caltrop family, Zygophyllaceae. The approximately 17 species it contains are native to tropical and warm temperate regions of the Americas. The flower and fruit morphology is similar to Tribulus. The convex fruits separate into about 10 nutlets each with one seed. The genus is named after A. Kallstroem who lived in the 18th century.

Larrea is a genus of flowering plants in the caltrop family, Zygophyllaceae. It contains five species of evergreen shrubs that are native to the Americas. The generic name honours Spanish scientist J.A. de Larrea. South American members of this genus are known as jarillas and are so closely related that hybrids are partially fertile. One of the more notable species is the Creosote Bush (L. tridentata) of the southwestern United States and northwestern Mexico The King Clone ring in the Mojave Desert is a Creosote Bush clonal colony estimated to be 11,700 years old.

Malacocarpus
Parodia is a of cacti. This genus has about 50 species, ranging from small globose plants to 1-m tall columnar cacti. [more]
Tribulus is a genus of plants found in many warm regions. The best-known member is T. terrestris (puncture vine), a widespread weed and also the source of a dietary supplement. T. terrestris has been said to raise natural testosterone levels if taken as a supplement. There have been no studies that show a direct correlation between the use of tribulus and an increase in natural testosterone. [more]
