A compound leaf is a single leaf that is divided into leaflets, or structures that themselves looks like individual leaves. Compound leaves can come in many forms, but the basic types are pinnate, palmate, and ternate (also known as trifoliate).Leaf shape can vary considerably. The most common shapes include oval, truncate, elliptical, lanceolate, and linear. Leaf tips and bases may also be unique, with names based on their shapes.The most common leaves are the kind you find on angiosperms, or flowering plants.

Is 4 leaf or 3 leaf rare?
The Rarity of the Four-Leaf Clover Finding a four-leaf clover is no small feat—estimates suggest that roughly only one in every 5,000 clovers has more than three leaves. Most clovers are the white clover, or Trifolium repens species, which naturally has just three leaves. As stated, clovers can have more than four leaflets. Some 4-leaf clover collectors, particularly in Ireland, regard the 5-leaf clover, known as a rose clover, as a particular prize.

On the lamina part of the leaf, there is a mid-rib or main vein passing through the centre of the lamina. Apex: tip of the leaf • Margin: edge of the leaf • Veins: carry food/water throughout leaf; act as a structure support • Midrib: thick, large single vein along the midline of the leaf • Base: bottom of the leaf • Petiole: the stalk that joins a leaf to the stem; leafstalk • Stipule: the small, leaf-like appendage to a .The arrangement of veins on a leaf is called venation. There are two types of venation: Parallel venation and reticulate venation.
