Tetragonia tetragonioides (previously T. expansa) is a leafy groundcover also known as Botany Bay spinach, Cook's cabbage, kōkihi (in Māori), New Zealand spinach, sea spinach, and tetragon. Its Australian names of warrigal greens and warrigal cabbage come from the local use of warrigal to describe plants that are wild (not farmed originally). It is native to Argentina, Australia, Chile, Japan, and New Zealand.
