Cotton Flower

Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose and may contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, cotton bolls facilitate the dispersal of the seeds.
