This member of the Oxalidaceae family was given this name by Marie Jules César Lélorgne de Savigny in 1798. It is found in Argentina, Paraguay, Uruguay and Brazil - and brought around the world, growing in a sandy or other well drained soil with some water and lots of sun. The caudex can grow to four centimetres in diameter, fifteen centimetres long, the entire plant to 20 or 30 centimetres in height. The flowers are from white over pink to violet.

The genera name means 'sharp, pungent', as to leaf taste. The species name means 'jointed'; separating freely as in leaf fall.
