The sepal is one of the scales that forms the calyx, the outside covering of the bud. Inside the calyx are the petals, variously formed and colored, which have two functions - protect the inner parts of the flower from damage until pollination can take place and attract bees or other pollinating agents to the inner parts of the flower. Next come the stamens or the male parts of the flower and on top of each stamen is a sac-like anther which produces the pollen grains. When the pollen grains are mature, the anther opens and the pollen is discharged. The pollen is transferred from the anther to the stigma, the sticky end of the pistil, or innermost part of the flower.
