Capparoidae

Capparoidae is a subfamily within the flowering plant family Capparaceae. This subfamily is characterized by several distinct morphological features, although variations exist within its diverse genera. Typically, members of Capparoidae are herbaceous plants, shrubs, or small trees, often found in tropical and subtropical regions.

The leaves of Capparoidae species are usually simple or palmately compound, and are alternately arranged on the stem. A significant characteristic is the presence of stipules, which are small leaf-like appendages at the base of the leaf stalk. These stipules can be persistent or caducous, meaning they fall off early.

Flowers in Capparoidae are generally bisexual and actinomorphic, exhibiting radial symmetry. They typically possess four sepals and four petals, though these can sometimes be reduced or absent in certain species. The stamens are numerous and often prominently displayed, a feature that gives the family its common name, the caper family, referring to the edible caper which is a flower bud. The ovary is usually superior, and the fruit is a capsule or a berry, which can vary greatly in size and shape depending on the genus.

The subfamily Capparoidae encompasses several genera, including Capparis, the type genus, which includes the common caper. Other notable genera within this group include Boscia and Cadaba. These plants have diverse ecological roles and are found in a variety of habitats, from arid regions to forests. Some species are of economic importance for their edible fruits, medicinal properties, or ornamental value.
