Definition of inflorescence in English:



  • 1The complete flower head of a plant including stems, stalks, bracts, and flowers.

    • ‘Each genus was further subdivided into three sections based on number of flowers per inflorescence, bract shape, size, and texture, degree of style fusion, and capsule shape.’
    • ‘Less coherent expression was detected in the endodermis of the root elongation zone, in the stem of the young inflorescence, pollen tubes, base of axillary buds, ovules, chalazal endosperm, and fruit abscission zone.’
    • ‘Indeed, shading the leaves reduces photosynthesis and carbohydrate supply to the developing inflorescences, causing flower abscission and lower yields.’
    • ‘Pistillate flowers are initiated on the lower portion of the inflorescence and staminate flowers are initiated on the distal portion.’
    • ‘Flowers are generally borne solitarily in leaf axils or in inflorescences subtended by bracts, but some taxa are ebractate.’

Mid 18th century (denoting the arrangement of a plant's flowers): from modern Latin inflorescentia, from late Latin inflorescere ‘come into flower’, from Latin in- ‘into’ + florescere ‘begin to flower’.
