Brit.

/pᵻˈdʌŋkl/, U.S.

/ˈpiˌdəŋk(ə)l/,

/piˈdəŋk(ə)l/

Origin: A borrowing from Latin. Etymon: Latin pedunculus.

Etymology: < post-classical Latin pedunculus stalk, footstalk (1686 or earlier) < classical Latin ped- , pēs foot (see -ped comb. form) + -unculus -uncle suffix. Compare French pédoncule protuberance of the brain (1735 as peduncles , plural), connection between parts of the nervous system (1765), stalk of a flower or fruit (1778). Compare also pedicel n., pedicle n.²Compare post-classical Latin pedunculus louse (6th cent.), alteration of classical Latin pēdiculus pedicle n.¹

1. Botany. The stalk of a flower or fruit, or of a cluster of flowers or fruits; (now) spec. the main stalk or primary axis of an inflorescence. Also: a stalk bearing a fungal fructification (rare). Cf. pedicel n. 1, pedicle n.² 1.

1753 Chambers's Cycl. Suppl. Peduncle, among botanists, expresses that little stalk which grows from the trunk or branches of a plant, and supports the parts of fructification, the flower and the fruit, or either.

1789 W. Jones Sacontalá vi. ii. 143 The artist had omitted a Sirísha-flower with its peduncle fixed behind her soft ear.

1830 J. Lindley Introd. Nat. Syst. Bot. 139 Leaves either opposite or alternate; in the latter case opposite the peduncles.

1874 M. C. Cooke Fungi 39 In all the Pucciniæi, the peduncles are permanent.

1902 Times 19 Sept. 10/4 The flowering-stem and peduncle..exhibited, as a rule, most clearly the primitive structure which in the vegetative parts had become obscured.

1957 Fassett's Man. Aquatic Plants (rev. ed.) 99 Flowers on stout peduncles, white; peduncles recurving as the fruit matures.

1993 Wildflower Spring 4/2 I feel that the traditional depiction of a plant, a botanical drawing accurate to the last peduncle..often misses the point about a wildflower.

2. Anatomy. A connection between a particular region of the brain and the rest of the brain; (more generally) a bundle of nerve fibres connecting two parts of the central nervous system. Cf. crus n. 2b.
