Peduncle
Peduncle Pe*dun"cle, n. [Formed fr. (assumed) L. pedunculus, dim. of pes, pedis, a foot: cf. F. p['e]doncule.] 1. (Bot.) The stem or stalk that supports the flower or fruit of a plant, or a cluster of flowers or fruits. [1913 Webster]

Note: The ultimate divisions or branches of a peduncle are called pedicels. In the case of a solitary flower, the stalk would be called a peduncle if the flower is large, and a pedicel if it is small or delicate. [1913 Webster]

2. (Zo["o]l.) A sort of stem by which certain shells and barnacles are attached to other objects. See Illust. of {Barnacle}. [1913 Webster]

3. (Anat.) A band of nervous or fibrous matter connecting different parts of the brain; as, the peduncles of the cerebellum; the peduncles of the pineal gland. [1913 Webster]
