Carrot, Daucus carota, is an edible, biennial herb in the family Apiaceae grown for its edible root. The carrot plant produces a rosette of 8–12 leaves above ground and a fleshy conical taproot below ground. The plant produces small (2 mm) flowers which are white, red or purple in color. The root can grow to between 5 and 50 cm (2.0–20 in) long and reach 5 cm (2.0 in) in diameter. The foliage of the plant can reach a height of 150 cm (59.1 in) when in flower. The carrot plant can be annual or biennial and may also be referred to as wild carrot. The plant is believed to have originated in Europe or the Western Mediterranean.
The Guar or cluster bean (Cyamopsis tetragonoloba) is an annual legume and the source of guar gum. It is also known as Gavar, Guwar or Guvar bean. This legume is a very valuable plant within a crop rotation cycle, as it lives in symbiosis with nitrogen-fixing bacteria.
It is an annual, with erect stems, 1 to 3 feet high, slender and branched. The lowest leaves are stalked and pinnate, the leaflets roundish or oval, slightly lobed. The segments of the uppermost leaves are linear and more divided. The flowers are in shortly-stalked umbels, five to ten rays, pale mauve, almost white, delicately pretty. The seed clusters are very symmetrical and the seeds fall as soon as ripe. The plant is bright green, shining, glabrous and intensely foetid.
Gawar beans are small to medium in size, averaging 3-10 centimeters in length, and are long and narrow with tapered ends. The smooth pods are green when young and have a slightly slimy, soft texture. As the pods mature, they transform into a yellow-green, and beneath the smooth skin, there are visible clustered seeds. Each pod contains 5-12 seeds that can range in color from black, white, grey, to pink.
