Prosopis is a genus of flowering plants in the family Fabaceae. It contains around 45 species of spiny trees and shrubs found in subtropical and tropical regions of the Americas, Africa, Western Asia, and South Asia. They often thrive in arid soil and are resistant to drought, on occasion developing extremely deep root systems. Their wood is usually hard, dense and durable. Their fruits are pods and may contain large amounts of sugar. The generic name means "burdock" in late Latin and originated in the Greek language.
The Portulacaceae are a family of flowering plants, comprising 115 species in a single genus Portulaca. Formerly some 20 genera with about 500 species, were placed there, but it is now restricted to encompass only one genus, the other genera being placed elsewhere. The family has been recognised by most taxonomists, and is also known as the purslane family. It has a cosmopolitan distribution, with the highest diversity in semiarid regions of the Southern Hemisphere in Africa, Australia, and South America, but with a few species also extending north into Arctic regions. The family is very similar to the Caryophyllaceae, differing in the calyx, which has only two sepals.
Conyza is a genus of flowering plants in the family Asteraceae.
Zornia is a cosmopolitan genus of herbs from the legume family Fabaceae. It was recently assigned to the informal monophyletic Adesmia clade of the Dalbergieae.
Azorella is a genus of flowering plants in the family Apiaceae, native to South America, New Zealand, southeastern Australia, and the islands of the Southern Ocean.
Machaerium is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. It contains the following species:
Haplopappus is a genus of flowering plants in the family Asteraceae found in South America, mostly restricted to the dry regions of the Southern Andes, Chilean Matorral, and Patagonia.
Nassauvia is a genus of flowering plants in the tribe Nassauvieae within the family Asteraceae. It is native to Argentina, Bolivia, Chile and the Falkland Islands.
Anarthrophyllum is a genus of flowering plants in the family Fabaceae. It belongs to the subfamily Faboideae.
The tribe Dalbergieae is an early-branching clade within the flowering plant subfamily Faboideae. Within that subfamily, it belongs to an unranked clade called the dalbergioids. It was recently revised to include many genera formerly placed in tribes Adesmieae and Aeschynomeneae and to be included in a monophyletic group informally known as the dalbergioids sensu lato. The members of this tribe have a distinctive root nodule morphology, often referred to as an "aeschynomenoid" or "dalbergioid" nodule.
Leucheria is a genus of flowering plants in the family Asteraceae.
