Sepal Sepal A sepal ( or ) is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom. The term "sepalum" was coined by Noël Martin Joseph de Necker in 1790, and derived from the Greek σκεπη ("skepi"), a covering. Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word "calyx" was adopted from the Latin "calyx", not to be confused with "calix", a cup or goblet. "Calyx" derived from
Nemophila breviflora long, pointed, and edged with stiff hairs, and there are reflexed appendages between the sepals. The bell-shaped flower corolla is white or purple-tinged and a few millimeters wide. The fruit is a capsule which develops within the calyx of sepals and contains a single red, pitted seed. Nemophila breviflora Nemophila breviflora is a species of flowering plant in the borage family known by the common names basin nemophila, Great Basin nemophila, and Great Basin baby-blue-eyes. It is native to southwestern Canada and the northwestern United States, where it generally grows in wooded and forested areas in thickets and moist streambanks.
