1. | Ovules are attached to the central axis of the ovary. |
2. | Ovules are attached to the free central placenta which is not connected to the ovary wall. |
3. | Ovules are attached to the walls of the ovary or to the extensions of it, and the ovary is unilocular. |
4. | Ovules are attached directly to the ovary wall and the ovary is typically one-chambered. |
