A fleuron, also known as printers' flower, 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: floron ("flower"). Robert Bringhurst in The Elements of Typographic Style calls the forms "horticultural dingbats". A commonly encountered fleuron is the ❦, the floral heart or hedera. It is also known as an aldus leaf.

In typography, a dingbat is an ornament, specifically, a glyph used in typesetting, often employed to create box frames, or as a dinkus. Some of the dingbat symbols have been used as signature marks or used in bookbinding to order sections.
