SpikeletSpikelet:
One or more florets that are subtended by a pair of bracts called glumes. Spikelets are pedicellate if located on a pedicle and sessile if attached directly to the rachis. Often spikelets with single florets have remnants of a second floret, usually a lemma.

Egg-shaped with basal end the broadest.
Brown glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it.

A small flower in a clustered inflorescence (e.g., sunflower, grasses). In grasses, a floret consists of the lemma, palea, stamens, and pistil.
