The guar bean or cluster bean (Cyamopsis tetragonolobus) is an annual legume and the source of guar gum. It grows best under conditions with frequent rainfall, but tolerates arid conditions well.[1] 80% of world production occurs in India, but, due to strong demand, the plant is being introduced into new areas. It is known as गवार् Gawaar in Hindi and Marathi, గోరు చిక్కుడు "Goruchikkudu kaya" or "Gokarakaya" in Telugu, Gorikayie in Kannada, and kotthavarai (கொத்தவரைக்காய்) in Tamil.
