Monocarpellary ovary, diadelphous androecium and marginal placentation is found in

Step-by-step solution

In Papilionaceae, only one carpel is present so a monocarpellary ovary is found. When inside of the stamens' filaments get fused and anthers remain free then that condition is called adelphous. When filaments form two bundles then that is known as diadelphous(9+1) condition. It is the subfamily of Leguminosae. In the unilocular ovary, marginal placentation is present. Ovules are present on the margin of the locule. In Cruciferae and Compositae, the gynoecium is bi-carpellary. In Liliaceae, the tricarpellary ovary i
