FAQ

Frequently Asked Questions

Not always. A pistil is a single carpel or a group of fused carpels. A gynoecium is the collective term for all the carpels in a flower. A simple gynoecium of one carpel is a pistil. A compound gynoecium of fused carpels is also called a pistil. However, if a flower has multiple separate, unfused carpels, the gynoecium is apocarpous and consists of multiple distinct pistils.

Primarily in Botany, Plant Biology, Horticulture, Agriculture, and Environmental Science. It is a standard term in the anatomical description of flowering plants (Angiosperms).

Most commonly with a soft 'g' /dʒɪ/ ('jih') or /dʒaɪ/ ('jy'). The hard 'g' /ɡaɪ/ ('guy') is a less common variant, primarily in American English. The standard UK pronunciation is /dʒɪˈniːsɪəm/.

The androecium, which is the collective term for all the stamens (male pollen-producing parts) of a flower.
