What does gynoecium mean?
The gynoecium is the collective term for the female reproductive structures of a flowering plant. It comprises one or more carpels, the basic female reproductive units of a flower; where a carpel is fully developed, it includes the stigma, style, and ovary. The word is also associated with the term pistil, although botanists may use pistil more broadly or differently depending on the context. Gynoecium is especially useful as the precise collective counterpart of the androecium, the male reproductive part of a flower. In descriptions of plant anatomy, it helps distinguish the arrangement, number, and maturity of the carpels. The term is primarily found in botanical and horticultural writing and is more technical than everyday speech. Its unusual name comes from Greek roots meaning “woman” and “little house,” a fittingly old-fashioned description of the flower’s female reproductive chamber.

"Each flower in the cluster has a well-developed gynoecium with a single carpel."
"In botanical descriptions, the colour and structure of the gynoecium are often used to distinguish closely related species."
The standard plural is gynoecia, pronounced /dʒaɪˈniːʃə/ in British English and /dʒaɪˈniːʃiə/ in American English.
"The species was distinguished by its gynoecia, each composed of several fused carpels."
The gynoecium is a flower’s female reproductive headquarters—and its name literally means “little house of the woman.”
