2. | Margin of the thalamus grows upward, enclosing the ovary completely, and other parts arise below the ovary. |
3. | Gynoecium is present in the center and other parts cover it partially. |
4. | Gynoecium is situated in the center, and other parts of the flower are located at the rim of the thalamus, at the same level. |
