Pistillate: It is a flower having carpels only. The female parts of a flower is called gynoecium and consists of pistils or carpels.

What Is a Pistillate Flower?

A female sex organ or female part of the flower is called a pistillate flower. A pistillate flower consists of pistils but no stamens. Pistils are capable of producing seeds. The pistil, the female reproductive part of a flower, is centrally located and consists of a swollen base called the ovary, containing potential seeds or ovules. Also, style or stalk arises from the ovary with a pollen-receptive tip known as the stigma that can be variably shaped or sticky, may be present.

During pollination, the compatible pollen grains reach the stigma and germinate to form a pollen tube. This pollen tube grows through the tissue of the style for depositing sperm for the fertilisation of the seeds or ovules in the ovary. Collective pistils then form the gynoecium in contrast to the male reproductive parts forming androecium.

Pistillate flowers are also unisex flowers like that of staminate flowers. but unlike staminate flowers these do have functionally active carpel, that is female reproductive parts of the flower. These flowers lack stamen. thus like staminate flowers, these will undergo self pollination when the staminate flower is present on the same plant.
