A fleuron is a typographic element, or glyph, used either as a punctuation mark or as an ornament for typographic compositions. Fleurons are stylized forms of flowers or leaves; the term derives from the Old French word floron for flower. Robert Bringhurst in The Elements of Typographic Style calls the forms "horticultural dingbats." It is also known as a printers' flower, or more formally as an aldus leaf (after Italian Renaissance printer Aldus Manutius), hedera leaf, or simply hedera (ivy leaf) symbol.
