| Leaf apex rounded | Referring to a leaf blade base that is curved at the apex with an angle greater than 90 degrees at the point where the two sides meet. |  |
| Leaf apex truncate | Referring to an apex or base that terminates abruptly in a nearly straight horizontal edge. | |
| Leaf asymmetrical | Referring to the form of a leaf in relation to the midrib, if the blade on each side of the midrib is unequal the leaf is asymmetrical. |  |
| Leaf base acute | Sharp; referring to the base of a leaf blade in which the two sides are straight and, when they meet, form an angle that is always less than 90°. |  |
| Leaf base asymmetric | Referring to a leaf base in which the two sides do not attach to the petiole at the same place, one is attached than the other. |  |
| Leaf base cordate | Heart-shaped at the base of a leaf blade. A cordate leaf blade always has a cordate base but a cordate leaf base may not always be associated with a cordate leaf blade. | |
| Leaf base cuneate | Wedge-shaped; referring to the base of a leaf blade of which the angle formed by the meeting of the margins is less than 90°. | |
| Leaf base decurrent | Referring to a leaf blade base that extends down the petiole. | |
| Leaf base lobate (lobed) | A rounded projection arising from the base of a leaf blade. | |
| Leaf base obtuse | Blunt, referring to the the base of a leaf blade in which the two sides are straight and, when they meet, form an angle greater than 90°. | |
| Leaf base rounded | Referring to a leaf blade base that is curved at the apex with an angle greater than 90 degrees at the point where the two sides meet. | |
| Leaf base sagittate | The base of a leaf blade shaped like an arrowhead. |  |
| Leaf base truncate | Referring to the base of a leaf blade that terminates abruptly in a nearly straight horizontal edge. | |
| Leaf blade | The expanded portion of a leaf, it and the petiole combined equal the leaf. Same as lamina. |  |
| Leaf flush | The expansion of new leaves. |  |
| Leaf flush | The expansion of new leaves. |  |
| Leaf gap | A region of parenchyma in the vascular tissue of a stem that is located above the level where a leaf trace diverges from the stem toward the leaf. |  |
| Leaf lamina | The expanded portion of a leaf, it and the petiole combined equal the leaf. Same as leaf blade. | |
| Leaf margin crenate | Referring to a leaf blade margin with teeth rounded at the apex. Compare with serrate. |  |
| Leaf margin dentate | Referring to a leaf margin with sharp teeth oriented at right angles to the central axis of the leaf blade. | |
