carpel: a unit of the female part of the flower (gynoecium), consisting of an ovary bearing one or more ovules, a receptive stigma, and often a stalk-like style between them. A flower can have a solitary carpel (and then the terms gynoecium and pistil are synonymous, Fig. 13 A & G) or more than one carpel. If the carpels (pistils) are free the gynoecium is apocarpous or if the carpels are fused the gynoecium (pistil) is syncarpous (or compound).
