| Crassinucellate ovules | The presence of two or more cell layers between the megasporophyte and the epidermal cells in the early development of the megasporophyte. The megasporophyte develops into the embryo sac which contains the egg that, if fertilized and the conditions are right, will develop into the embryo. |  |
| Ovules | Structures that arise from placentae in the ovary locules. Among other cells, the egg and two polar nuclei are found in the ovule. After fertilization, the egg develops into an embryo and the polar nuclei develop into endosperm which, along with the seed coat, form the seed.. |  |
| Ovules anatropous | Referring to a curved downwardly oriented ovule in such a way that the micropyle is close to the funicular attachment. |  |
| Ovules horizontally oriented | Ovules projecting outward at right angles from the vertical axis of the ovary. |  |
| Ovules obliquely oriented downward | | |
| Ovules obliquely oriented upward | Ovules projecting upward at less than right angles from the vertical axis of the ovary. | |
| Ovules pendulous | Ovules that hang downward from the septum at apex of the locule with the micropyle facing upward. |  |
| Ovules tenuinucellate | The presence of no cells or a single cell layer between the megasporophyte and the epidermal cells in the early development of the megasporophyte. The megasporophyte develops into the embryo sac which contains an egg that, if fertilized and the conditions are right, will develop into an embryo. | |
