Definition of spikelet in US English:



  • The basic unit of a grass flower, consisting of two glumes or outer bracts at the base and one or more florets above.

    • ‘From early summer on, stiff yellow stems are topped with purple spikelets.’
    • ‘Diseased spikelets may be entirely transformed into dark fungal spore masses.’
    • ‘The female flowers can be distinguished by long, silky hairs at the bases of the flower spikelets.’
    • ‘Similar results were presented in experiments where the sterilization of florets led to more grain setting and greater grain growth in the untreated spikelets.’
    • ‘At the base of each spikelet, there is a pair of sterile glumes that surrounds a series of flowers (five to eight in number).’
