Solution:

In Malvaceae, ovary is superior, has two to many carpels but usually 5 to 10 carpels and syncarpous. Ovary with two to many locules. Pentacarpellary is seen. Number of locules usually corresponds to number of carpels. Each locule contains one to many ovules on axile placentation. Style is long, slender and passes through the staminal tube ending in two to many distinct round stigmas. In Cruciferae or Brassicaceae, ovary is bicarpellary (tricarpellary in species of Lepidium, tetracarpellary in Tetrapoma and Tropidocarpum), syncarpous, carpels placed transversely. Ovary is bilocular due to the presence of a false septum called replum.
