The gynoecium in family-Cruciferae (Brassicaceae) is bicarpellary, syncarpous, ovary superior, unilocular with parietal placentation. At maturity ovary becomes bilocular due to formation of false septum (replum) eg, mustard.
In family-Asteraceae (Compositae) the gynoecium is bicarpellary, syncarpous, ovary inferior, unilocular, one ovule in each locule, basal placentation and stigma branched, eg, sunflower.
In family-Fabaceae (Leguminosae) the gynoecium is monocarpellary, unilocular with superior ovary and marginal placentation, eg, pea.
