Cupule

 

an organ that surrounds an entire fruit or only the base of a fruit. The cupule is formed by the proliferation of the fused bract and bractlets of pistillate flowers (for example, in the filbert and hornbeam). It may also be formed by the proliferation of the axils of the inflorescence on which the bracts and bractlets of undeveloped flowers appear in the form of nodules, scales, or needles (for example, in the oak). In the beech and chestnut, the axil of the inflorescence, in addition to the leaves, may take part in the formation of the cupule.
