The basic unit of a grass flower, consisting of two glumes or outer bracts at the base and one or more florets above.
- The female flowers can be distinguished by long, silky hairs at the bases of the flower 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).
- Similar results were presented in experiments where the sterilization of florets led to more grain setting and greater grain growth in the untreated spikelets.
