Berry (botany) in fruit type may have led to the evolution of fruit eating in mammals and birds. Fruit type has been considered to be a useful character in classification and in understanding the phylogeny of plants. The evolution of fruits with a berry-like pericarp has been studied in a wide range of flowering plant families. Repeated transitions between fleshy and dry pericarps have been demonstrated regularly. One well-studied family is the Solanaceae, because of the commercial importance of fruit such as tomatoes, bell peppers, and eggplants or aubergines. Capsules, which are dry dehiscent fruits, appear to be the original form of
Berry (botany) is given the special name "hesperidium". A specialized term, pepo, is also used for fruits of the gourd family Cucurbitaceae, which are modified to have a hard outer rind, but are not internally divided by septae. The fruits of "Passiflora" (passion fruit) and "Carica" (papaya) are sometimes also considered pepos. Berries that develop from an inferior ovary are sometimes termed epigynous berries or false berries, as opposed to true berries, which develop from a superior ovary. In epigynous berries, the berry includes tissue derived from parts of the flower besides the ovary. The floral tube, formed from the basal part
