• Bur is a fruit with open hooked or barbed spines or appendages.
• Caryopsis or Grain is a seed-like fruit resembling an achene but having the seed coat firmly united with the ovary wall.
• Nut is a one-seeded fruit that resembles an achene, but larger and has a long shell, with much thickened, hard pericarp.
• Samara is a winged achene.
• Schizocarp is a dry fruit that splits along one-seeded carpels or parts.

• Capsule is a fruit that is derived from two or more united carpels and splitting in various ways.
• Legume or pod is a dehiscent fruit derived from a single carpel and splits open along 2 seams or sutures.
• Silique is an elongated, two-locular fruit with 2 parietal placentae, and usually within 2 valves separating from the persistent placentae and septum as in Brassicaceae.
• Dry fruits are fruits in which the entire pericarp becomes dry, often brittle or hard at maturity.
• Dehiscent dry fruits are fruits that split open along definite points at maturity.
• Indehiscent dry fruits are dry fruits that do not split open along definite sutures at maturity.
• Fleshy fruits are a general term to refer to fruits where all or most of the pericarp is soft and fleshy at maturity.

• Simple fruit is a fruit that results from the ripening of a single ovary.
• Compound fruit is when the fruit develops from several ovaries.
• Aggregate fruit is a fruit that develops from several ovaries that belong to a single flower and becomes crowded into a mass, these are joined together by a common receptacle.
• Multiple or collective fruit is a fruit that is derived from the ovaries of several flowers that unite into a mass.
• Accessory fruit is fruit that develops from other parts of the flower other than the ovary.
• Fruits are the mature ovaries or pistils of flowering plants plus any associated accessory parts.
