The Citrus family is a valuable source of edible fruits and ornamentals. These members of the Plantae division are usually woody shrubs, trees, or hebaceous perennials. There are nearly 160 genera and 1,700 species included in this family. The citrus flowers are often sweet-scented and are usually angiosperms. Citrus flowers typically have 4 or 5 petals and sepals and 8-10 stamen. The flowers usually have a single stigma with 2 to 5 united carpels. The leaves on citrus plants are usually compound and do not have stipules. Pellucid glands are oil containing cavities that are responsible for the aromatic smell of the citrus family members, which are located on the plants’ leaves. These pellucid glands were traditionally the primary characteristic for identifying the Rutaceae.
