Etymology: Polypetaly is a botanical term for a flower whose petals are separate from one another, rather than fused into a tube or cup. It is built from two Greek elements: "polys", meaning "many", and "petalon", meaning "leaf" or "petal", the latter from "petannynai", "to spread out". The ending "-y" turns the adjective "polypetalous" into a noun for the condition itself. The contrast it names is between polypetalous flowers, such as a rose or buttercup, and gamopetalous ones, whose petals grow together. Botanists use these categories to sort flowering plants into groups, and the terms belong to the scientific vocabulary of plant classification that developed in the 18th and 19th centuries, when Linnaean taxonomy made precise descriptions of flower structure essential.
