Definition of sympodium in US English:

sympodium

noun

Botany
  • The apparent main axis or stem of a plant, made up of successive secondary axes due to the death of each season's terminal bud, as in the vine.

    • ‘A sympodium is generally defined as an axial bundle and its associated leaf and branch traces.’
    • ‘Since the lateral axes have more or less the same pattern of arrangement of sympodia as the main axis, the number of branch bundles is related to the number of bundles within the leaf vascular supply characteristic for that species.’
    • ‘The sympodia are arranged more or less parallel to the stem axis and follow the phyllotactic spirals of the leaves.’
    • ‘Each module of a sympodium consists of an axis bearing two bracts and terminating in a flower.’
    • ‘In the second treatment, the main stem leaf subtending the sympodium was treated.’
