| One of these determinables is number of cotyledons under which fall the determinates acotyledon, monocotyledon, and dicotyledon. |
| Sandersonia aurantiaca is a liliaceous monocotyledon with a bell-shaped corolla formed from fused petals and sepals. |
| However, it should be kept in mind that young leaves of dicotyledons are more heterogenous as to cell age, than sections of a monocotyledon leaf. |
| The term monocotyledon is applied to these plants because the embryo has only one cotyledon or seed-leaf. |
| Taxonomically, the three wood species are respectively gymnosperm, monocotyledon and dicotyledon. |
