“footstalk of a leaf,” 1753, from French pétiole (18c.), from Late Latin petiolus, misspelling of peciolus “stalk, stem,” literally “little foot,” diminutive of pediculus “foot stalk,” itself a diminutive of pes (genitive pedis) “foot” (see foot (n.)). Given its modern sense by Linnaeus.

A stem or pedicle.
