A gynoecium (from Ancient Greek gyne, "woman") is the female reproductive parts of a flower. The male parts are called the androecium. Some flowers have both female and male parts, and some do not.
Another key term is carpel. Carpels are the building blocks of a pistil. The gynoecium may have one pistil or more. A pistil may have one carpel or more than one stuck together ("fused"). Carpels and pistils have three parts: a stigma at the top where the pollen lands; a style and an ovary. In the case of a pistil, the stigma, style, and ovary may be made up of those parts of more than one carpel, fused.
Plant ovaries are the parts of the gynoecium which (much like animal ovaries) contain ovules. The style is generally stalklike. It is between the ovary at the bottom and the stigma at the top. In some plants, there are no styles in the pistils. The stigma is the pollen receptor at the top of the carpel. Stigmas may be separate or they may be in a region called the "stigmatic region".[1]
