| Leaf venation cladodromous | Referring to a type of leaf venation in which the secondary veins branch freely before they reach the margin. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. |  |
| Leaf venation eucamptodromous | Referring to a type of leaf venation in which the secondary veins do not reach the margin and do not form a series of prominent arches. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. |  |
| Leaf venation eucamptodromous | Secondaries upturned and gradually diminishing apically inside the margin but not connecting to the secondary above it. Based on (Hickey, 1973. For more information about leaf venation see Ellis et al. (2009). |  |
| Leaf venation flabellate | Referring to leaf venation with several to many fine basal veins that spread out from the base like a fan and divide somewhat toward the apex. Based on Ellis et al., 2009. |  |
| Leaf venation hyphodromous | Referring to a leaf blade with all but the midvein absent or not visible because the leaf blade is too fleshy for them to be seen. |  |
| Leaf venation imperfect acrodromous | Referring to a type of leaf venation in which two or more primary or strongly developed secondary veins arch upward from or above the base and do not converge at the apex. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. |  |
| Leaf venation mixed craspedodromous | Referring to a type of leaf venation in which some of the secondary veins terminate at the leaf margins and the remainder of the secondary veins do not, e.g. half of the secondary veins are craspedodromous and the other half camptodromous. |  |
| Leaf venation perfect acrodromous | Referring to a type of leaf venation in which two or more primary or strongly developed secondary veins arch upward from the base or above the base and converge near the apex. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. |  |
| Leaf venation reticulodromous | Referring to a leaf venation type in which the secondary veins form a network of veins soon after departing from the midrib. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. | |
| Leaf venation simple craspedodromous | Referring to a type of leaf venation in which all of the secondary veins terminate at the leaf margins. |  |
| Leaf venation suprabasal acrodromous | Referring to a type of leaf venation in which two or more primary or strongly developed secondary veins arch upward from above the base. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. | |
| Leaf venation suprabasal actinodromous | Referring to a type of leaf venation in which three or more primary veins diverge radially from a single point above the point of attachment of the petiole. |  |
| Marginal leaf vein | A leaf vein that runs more-or-less parallel to the margin of a leaf. |  |
| Odd-pinnate leaf | Pinnate with an odd number of leaflets; i.e., without a terminal leaflet. Same as imparipinnate. |  |
| Paripinnate leaf | Pinnate with an even number of leaflets; i.e., without a terminal leaflet. Same as even-pinnate and parapinnate.. |  |
| Peltate leaf | Referring to a leaf blade attached to the petiole by its lower surface rather than its margin; for example species of Nymphaea glandulifera, Hydrocotyle umbellata, and those illustrated for this term. |  |
| Simple leaf | Referring to a leaf that is not divided into smaller units. Opposite of compound. |  |
| Tendril leaf opposed | A tendril that arises opposite the insertion of a leaf; for example, Parthenocissus quinquefolia and many othe species of Vitaceae. |  |
| Tripinnately compound leaf | A compound leaf divided into three parts, each of which is pinnately compound. | |
| Unifoliolate leaf | A leaf appearing to be simple but believed to be derived from an ancestor with a compound leaf, commonly found in species of Fabaceae. |
