The gynoecium may present as one or more uni-carpellate pistils or as one multi-carpellate pistil. (The number of carpels is denoted by terms such as tricarpellate (three carpels).) Carpels are thought to be phylogenetically derived from ovule-bearing leaves or leaf homologues ( megasporophylls ), which evolved to form a closed structure ...
The gynoecium consists of three parts: the ovary, bulging lower part that forms a cavity or locule inside which are the ovules; the style which is a more or less elongated column that supports the third component of the pistil: the stigma. This is constituted by a specialized glandular tissue for the reception of the grains of polen.

Gynoecium – the whorl of carpels; may comprise one (syncarpous), or more (apocarpous), pistils, each pistil consisting of an ovary, style, and stigma. Apocarpus – the gynoecium consists of more than one pistil. Cell – Compound pistil – Funicle – the stalk that connects the ovule to the placenta. Funiculus –
The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each ...
The gynoecium, consisting of one or more carpels, is the female part of the flower found on the innermost whorl. Each carpel consists of a stigma, which receives pollen, a style, which acts as a stalk, and an ovary, which contains the ovules. [2] Carpels may occur in one to several whorls, and when fused are often described as a pistil.
The good news for the milkvetch plant is that they usually need wildfire to sprout — meaning dormant seeds now have a massive new habitat for a new crop of the rare shrub.
The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of stigmatic papillae , the cells of which are receptive to pollen.
