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.
Lanceolate
Brown spikeletsSpikelet:
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. and appendages are dark brown.
Smooth
Papery, enclosed in glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it.

Rachis segmentRachis segment:
A segment of the central axis of the inflorescence (rachis). In some species (e.g. Andropogon) separation of the sessile spikelets occurs when the rachis disarticulates at the spikelet bases leaving the segment of the rachis between spikelets attached to the lower spikelet.
, pedicelPedicel:
The stalk within an inflorescence supporting a single flower or spikelet.

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