polyphyllous
Polyphyllous is a term used in botany to describe a type of leaf arrangement in plants. In polyphyllous leaves, the leaflets are arranged in a whorled or spiral pattern around the stem. This arrangement is distinct from monophyllous leaves, which have a single leaf blade, and biphyllous leaves, which have two leaflets. Polyphyllous leaves are often found in plants that are deciduous, meaning they shed their leaves annually. Examples of plants with polyphyllous leaves include certain species of maple, oak, and willow. The term "polyphyllous" comes from the Greek words "poly," meaning many, and "phyllon," meaning leaf. This arrangement allows for efficient use of sunlight and space, as the leaves are not crowded together, which can help prevent shading and competition for resources.
