sepal
Sepals are plant tissues, which refer to the outermost ring of flowers and can protect the inside of flower buds. A circle of complete sepals forms a calyx. It is often green. Sepals separated from each other are called calyx, sepals combined with each other are called calyx, the lower end of calyx is called calyx tube, and the upper part is called calyx lobe; The outer ring of two calyx lobes is called accessory calyx, such as Malvaceae.
Sepals usually fall early, but some still exist after flowering, such as persimmon, eggplant and tomato, which are called persistent sepals or persistent calyx. Sepals are three outer tepals. The central 1 piece is called the middle sepal or the back sepal, which is the "main petal" in ancient books; Two lateral sepals are called lateral sepals, which are called "lateral petals" in ancient books. In Paphiopedilum papyrifera and Cyperus sedge, two lateral sepals are combined to form 1 sepals in different degrees, which is called combined sepals.
