Dry: split/nonsplit
Fleshy: berry, drupe herperidium (pericarp well developed)
Endocarp: “skin “ around the seed
Mesocarp: fleshy part around seed
Exocarp: outer skin
Accessory: one ovary plus other tissues
Aggregate: many ovaries in one flower
Multiple : combined from a cluster of flowers with individual ovaries
