cypsela
Cypsela is dry, indehiscent, single-seeded fruit develops from an unilocular, single ovulate inferior ovary of bicarpellary, syncarpous, gynoecium possessing basal placentation. The fruit wall develops from pericarp and thalamus and is thin and remains attached to the seed at one point, eg, Helianthus.
Caryopsis are dry, indehiscent, the small single-seeded fruit develops from unilocular single ovule, superior ovary of the multi carpellary gynoecium. It differs from typical achenes as their pericarp is completely fused with the seed coat or testa, eg, Poaceae.
Cremocarp is bilocular and two seeded schizocarpic fruits (small, dry) developed from the inferior ovary of bis carpellary, syncarpous gynoecium possessing persistent stylopodium, eg, Apiaceae.
Berry is fleshy, indehiscent, few to multi-seeded fruit derived from multi carpellary syncarpous gynoecium.The fleshy pericarp of berry consists of epicarp. Mesocarp and endocarp.
