Quick Summary

In botany, a peduncle is the stalk that supports a single flower or an inflorescence. It originates from the New Latin word pedunculus, a diminutive of the Latin word ped- meaning "foot". Essentially, it's a "footstalk".12

When a flower grows alone, the peduncle is the stem segment between the receptacle (where floral organs attach) and the bract. If flowers are arranged in an inflorescence, the peduncle is the main stalk supporting the entire cluster. Individual flowers within that cluster are then supported by smaller stalks called pedicels. The term peduncle can also refer to a slender part that attaches a larger part in anatomy, such as in insects.123
