Fagonia is a genus of wild, flowering plants in the caltrop family, Zygophyllaceae, having about 34 species. The latest reorganization of the genus took place in 2018 when systematists Christenhusz & Byng, Royal Botanical Gardens, Kew (UK) included Fagonia spp.. along with several other Zygophyllum genera, into a new genus named "Zygophyllum L." Species occurring in the US are commonly referred to as fagonbushes. The distribution of the genus includes parts of Africa, the Mediterranean Basin, the Mid-East, India, and parts of North & South America. Fagonia species have been used ethnobotanically by traditional practitioners under Ayurvedic and other TM healing regimes for many maladies. Species occur in deserts, dry washes, ditches and on rocky outcrops, including at altitude.
Fagonia laevis is a perennial herb of the United States desert southwest. It has opposite leaves, trifoliate with spinescent stipules, a lavender corolla and smooth fruits. Under cultivation, F. indica has been found to have a long taproot and to its growth slowing where temperatures dipped below 65 F.
Commercial Fagonia products available on the web should be viewed with caution by reason of there being little to no authentication as to species contained therein, based on DNA analysis. It may be that all Fagonia species contain similar medicinal compounds but that has yet to be established as of 2015 [update] . Research carried out at Quaid-i-Azam U. in Pakistan found that three Pakistani Fagonia species, both the verified (per B.-A. Beier's 2005 reorganization of the genus) and unverified ones, [3] were represented in commercial Fagonia (Dramas) products in the Islamabad marketplace. Plant systematists[ who? ] caution that species other than Fagonia, as well as other, unrelated material, can be present in commercial preparations.
Numerous scientific papers cite Fagonia cretica as the species studied. However, due to the re-ordering of Fagonia species by Beier in 2005, researchers have found that they have actually been studying another Fagonia species, instead, most commonly, Fagonia indica. [3]
In 2022, researchers at the Linus Pauling Institute, Oregon State U., determined that an acid-hydrolyzed extract of F. indica was much more effective than an aqueous extract at causing MCF-7 breast cancer cell death and inhibiting further cell multiplication.
As of February 2025 [update] , Plants of the World Online considered Fagonia to be a synonym of Zygophyllum . [1] Species formerly placed in Fagonia include:
Zygophyllaceae is a family of flowering plants that contains the bean-caper and caltrop. The family includes around 285 species in 22 genera.
Phlomis is a genus of over 100 species of herbaceous plants, subshrubs and shrubs in the mint family Lamiaceae, native from the Mediterranean region east across central Asia to China.
Anthemis is a genus of aromatic flowering plants in the family Asteraceae, closely related to Chamaemelum, and like that genus, known by the common name chamomile; some species are also called dog-fennel or mayweed. Anthemis are native to the Mediterranean region and southwest Asia east to Iran. A number of species have also become naturalized in the United Kingdom and other parts of the world.
Tribulus is a genus of plants in the family Zygophyllaceae and found in diverse climates and soils worldwide from latitudes 35°S to 47°N. The best-known member is T. terrestris, a widespread invasive species and weed.
Helianthemum, known as rock rose, sunrose, rushrose, or frostweed, is a genus of about 110 species of flowering plants in the family Cistaceae. They are widely distributed throughout the Northern Hemisphere, especially in the Mediterranean.
Trigonella is a genus from the family Fabaceae. The best known member is the herb fenugreek. Members of the genus occur naturally in the Canary Islands, southern Europe, non‑tropical Africa, western and central Asia, the Indian subcontinent, and Australia.
The genus Securigera contains a number of plant species commonly referred to as crownvetch. It is a segregate of the genus Coronilla. The name Securigera was first published by A. P. de Candolle in 1805 with the single species Securigera coronilla, which is now considered to be a synonym of Securigera securidaca(L.) Degen & Dörfl. (1897), based on the earlier publication of the same taxon as Coronilla securidacaL. in 1753.
Erodium is a genus of flowering plants in the botanical family Geraniaceae. The genus includes about 120 species with a subcosmopolitan distribution, native to Europe, North Africa, Asia, Australia, and more locally in North and South America. They are perennials, annuals, or subshrubs, with five-petalled flowers in shades of white, pink, and purple, that strongly resemble the better-known Geranium (crane's-bills). In English-speaking areas of Europe, the species are known as stork's-bills. In North America they are known as filarees or heron's bill.
Zygophyllum is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek words ζυγόν (zygon), meaning "double", and φυλλον (phyllon), meaning "leaf". It refers to the leaves, each of which have two leaflets.
Roepera similis is a succulent annual herb native to Australia.
Frankenia is the only genus in the Frankeniaceae family of flowering plants. Other genera have been recognized within the family, such as Anthobryum, Hypericopsis and Niederleinia, but molecular phylogenetic studies have consistently shown that they all belong inside Frankenia. Frankenia comprises about 70–80 species of shrubs, subshrubs and herbaceous plants, adapted to saline and dry environments throughout temperate and subtropical regions. A few species are in cultivation as ornamental plants.
Zygophyllum album is a species of plant in the family Zygophyllaceae which is found in arid regions of Africa and the Arabian Peninsula. It is a salt tolerant plant and dominates many of the plant communities in which it grows.
Zygophyllum fontanesii, synonym Tetraena fontanesii, is a species of plant of the family Zygophyllaceae. It is found in Macaronesia and northwest Africa.
Tetraena is a possible genus of flowering plants in the family Zygophyllaceae, subfamily Zygophylloideae. As of January 2025, Plants of the World Online and the World Flora Online accepted it as a synonym of Zygophyllum.
Roepera is a genus of flowering plants in the family Zygophyllaceae, subfamily Zygophylloideae. It is native to Australia and south-western Africa, from Angola to South Africa.
Anthemis cretica, the Cretian mat daisy or white mat chamomile, is a species of flowering plant in the family Asteraceae. It or its many subspecies can be found around the Mediterranean region, the Black Sea area, Poland, the Caucasus, and the Middle East as far as Iran. It is highly morphologically variable, and the namesake of a species complex.
Augea is a possible monotypic genus of flowering plants in the family Zygophyllaceae. Its only species is Augea capensis, native to Namibia and the western Cape Province of South Africa. The genus and species were first described by Carl Peter Thunberg in 1794.
Zygophyllum dumosum, the bushy bean-caper, is a species of flowering plant in the family Zygophyllaceae, native to Egypt, the Sinai Peninsula, and the Levant. It is a dominant shrub in the highlands of the Negev Desert.
Zygophylloideae is a subfamily of the family Zygophyllaceae. The subfamily comprises about 180 species of shrubs, subshrubs and herbs, found throughout arid parts of the Palaeotropics and into North and South America. As of February 2025, the division of the subfamily into genera is disputed, with between four and seven genera accepted by different sources.
