Leaf whorls on a herbaceous Lilium michiganense Leaf whorls on a woody tree, Brabejum stellatifolium In botany, a whorl or verticil is a whorled arrangement of leaves , sepals , petals , stamens , or carpels that radiate from a single point and surround or wrap around the stem or stalk.
Examples of trees with whorled phyllotaxis are Brabejum stellatifolium [4] and the related genus Macadamia. [5] A whorl can occur as a basal structure where all the leaves are attached at the base of the shoot and the internodes are small or nonexistent. A basal whorl with a large number of leaves spread out in a circle is called a rosette.
Compound leaves may be pinnate with pinnae (leaflets) on both sides of a rachis (axis), or may be palmate with multiple leaflets arising from a single point. [1] Leaf structure is described by several terms that include: Bipinnate leaf anatomy with labels showing alternative usages A ternate compound leaf with a petiole but no rachis (or rachillae)

In plant morphology, a cataphyll (sometimes also called a cataphyllum [1] or cataphyll leaf [2]) is a reduced, small leaf. [3] Many plants have both "true leaves" ( euphylls ), which perform most of the photosynthesis , and cataphylls, which are modified to perform other functions.
