Tetragonia is a genus of 51 species of flowering plants in the family Aizoaceae, native to temperate and subtropical regions mostly of the Southern Hemisphere, in New Zealand, Australia, southern and eastern Africa, and western South America, and eastern Asia.[1]
Description
Distribution
About forty species of Tetragonia are found in southern Africa, from Angola to South Africa.[2] They also occur in Australia,[3] eastern Africa (Kenya and Ethiopia), western south America (Peru and Chile), and Asia (Japan, Korea, Taiwan, southern China, Myanmar, and Vietnam).[1]
Classification
The genus was first formally described by the botanist Carl Linnaeus in 1753 in the work Species Plantarum.[3] Synonyms for the genus include Tetragonocarpos Mill., Demidovia Pall., and Tetragonella Miq.[1]
Human use and cultivation
The best known species of Tetragonia is the leafy vegetable food crop, Tetragonia tetragonoides ("New Zealand spinach"). New Zealand spinach is widely cultivated as a summer leafy vegetable. Some of the other species are also eaten locally, such as Tetragonia decumbens ("Dune spinach") which is a local delicacy in its native southern Africa.[4]
