There are three main types of venation in leaves:
✴In parallel - veined leaves, the veins run parallel to each other. This condition is characteristic of the monocotyledoneae. Parallel veins may run lengthwise on the leaf, as in Eucharis grandiflora (Amazon lily), or they may be parallel, but directed outward from the midrib to the margin (penniparallel).
✴Pinnately - veined leaves have a single primary vein or midrib, from which smaller veins branch off, like the divisions of a feather. Examples are Eriobotrya japonica (loquat) and Camellia japonica (camellia).
✴Palmately - veined leaves have several principal veins radiating from the base of the leaf blade, as in Acer rubrum (red maple) and Carica papaya (papaya).
