Aggregate fruit A fruit formed by the coalescence of carpels that were distinct (apocarpous) in flower; e.g., (blackberry) and (strawberry).. The fruit of a strawberry. Photos by S. A. Mori.

Capsule A dry, dehiscent fruit that develops from a syncarpous ovary; it can open in the middle of the locules (loculicidal), along the septa (septicidal), or around the circumference (circumscissile). Lateral view of a loculicidal capsule. Photo by S. A. Mori.
Carpophore A prolongation of the receptacle to which the carpels are attached; e.g., the expanded red structure bearing the fruits in Ouratea (Ochnaceae); the central axis of a fragmenting fruit (schizocarp) to which the separate parts are attached; e.g., the fruits of Apiaceae and some species of Sapindaceae (in this sense, same as columella). Lateral view of a loculicidal capsule. Photo by S. A. Mori.
Carpopodium Differentiated base of a cypsela (Asteraceae), commonly zygomorphic and occasionally sculptured. Lateral view of a loculicidal capsule. Photo by S. A. Mori.
Caryopsis A dry, hard, one-seeded, indehiscent fruit unique to the Poaceae in which the pericarp is adnate to the seed coat. Same as grain. Lateral view of a loculicidal capsule. Photo by S. A. Mori.
Cashew apple The swollen pedicel that subtends the fruit of Anacardium (Anacardiaceae). Scientifically called the hypocarp. Lateral view of a loculicidal capsule. Photo by S. A. Mori.
Circumscissile capsule Dehiscing via a line around a fruit with the top usually falling off like the lid of a jar. Immature fruit of Jeffersonia diphylla. Photo by S. A. Mori.
Coccus (plural = cocci) One of the parts of a dry fruit that breaks into usually 1-seeded segments; e.g., the fruit of Serjania spp. (Sapindaceae); in the Euphorbiaceae, one of the sections of the wall of a dry dehiscent fruit. Immature fruit of Jeffersonia diphylla. Photo by S. A. Mori.

Craspedium A legume pod in which the valves separate at maturity from the persistent septae or replum, and, as a rule, simultaneously break into one-seeded segments. Immature fruit of Jeffersonia diphylla. Photo by S. A. Mori.
Cupulate Bearing a cupule. Immature fruit of Jeffersonia diphylla. Photo by S. A. Mori.
Cupule A cup-shaped structure that usually subtends a fruit; e.g., that of many species of Lauraceae and Rhabododendron amazonicum. Cupule of a Lauraceae. Photo by S. A. Mori.
Cylindrical fruit A fruit that is much longer than it is broad. Fruit and leaves of Couratari guianensis. Photo by S. A. Mori.
Cypsela (plural = cypselae) A dry, indehiscent fruit derived from an inferior, bicarpellate ovary; e.g., in Asteraceae. Similar to an achene, but derived from an inferior ovary and attached to the fruit wall throughout, i.e., not at a single place as in an achene. A disk flower of an Asteraceae. Drawing by B. Angell.
Dehisce (dehiscent) Splitting open at maturity, usually applied to a fruit that opens to release seeds but other structures, such as sporangia may also be called dehiscent. Dehisced fruits of Celastrus orbiculatus. Image by S. A. Mori.
Diclesiuim A type of indehiscent anthocarp in which the perianth encloses or is accrescent around the pericarp and aids in dispersal. Dehisced fruits of Celastrus orbiculatus. Image by S. A. Mori.
Diclesium (pl. = diclesia) An indehiscent fruit (often an achene) surrounded by a free but persistent perianth. Dehisced fruits of Celastrus orbiculatus. Image by S. A. Mori.
