Sepal |
||
A sepal is a member of the outermost set of floral "leaves", often green. (Botanists consider petals and sepals to be modified forms of leaves.) The complete set of sepals of a flower is called the calyx. Some flowers lack petals, but if the sepals are brightly colored, they may appear to be petals. When both sepals and petals are both present, the sepals are located below or beneath the petals. |
