Extensive Definition

A leaflet in botany is a part of a compound leaf. A leaflet may resemble an entire leaf, but it is not borne on a stem as a leaf is, but rather on a vein of the whole leaf . Compound leaves are common in many plant families.
A tomato plant has leaflets on compound leaves.
Leaflets borne on the central vein of a leaf are referred to as pinnae; the compound leaves themselves are described as pinnate. A plant may be further subdivided in that the pinnae are themselves split into leaflets, or pinnules; these leaves are now twice pinnate, or bipinnate. A few plant species even have tripinnate leaves.
leaflet in Czech: Lístek
leaflet in German: Blättchen
leaflet in Spanish: Foliolo
leaflet in French: Foliole
leaflet in Polish: Listek
leaflet in Portuguese: Folíolo
