Petal Petal Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla. Petals are usually accompanied by another set of special leaves called sepals, that collectively form the "calyx" and lie just beneath the corolla. The calyx and the corolla together make up the perianth. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term "tepal" is appropriate include genera such as "Aloe"
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.
