Samara is a single seeded, dry indehiscent fruit. Its pericarp becomes membranous and flat-like wings that help in dispersal, e.,g. Ulmus, Holoptelia indica. A berry is a pulpy-indehiscent, few to multiseeded fruit derived from multicarpellary syncarpous gynoecmm.

Schizocarpic fruits are simple, dry, multiseeded fruits, which breakup into single seeded parts. The smgle seeded parts, which further do not dehisce are called mericarps. |
