In roses (the genus Rosa, Rosaceae), the flowers (left) have a large hypanthium that encloses the many distinct carpels. The sepals, petals, and stamens arise from around the top of the hypanthium, while the styles and stigmas protrude through the opening in the hypanthium. Each carpel matures (right) into an achene, and the achenes are enclosed by the red, fleshy hypanthium. The sepals, stamens, and styles persist at the top of the hypanthium. The arrows show what structures in the flower become what structures in the mature fruit. The whole rose fruit is called a "hip", and it is an accessory fruit. |
