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.
EllipticElliptic:
Outline of an ellipse; greatest width midway sloping to an equally pointed apex and base.
Brown glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it.
; yellow to gray floretsFloret:
A small flower in a clustered inflorescence (e.g., sunflower, grasses). In grasses, a floret consists of the lemma, palea, stamens, and pistil.

One of two bracts of the grass floret; it is located on the side nearest the embryo and opposite the rachilla.

One of the thin bracts of grass floret enclosing the fruit (caryopsis) that is located on the side opposite the embryo.
