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
Light brown
Smooth
Tissue-like, hidden beneath glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it.

Two appendages: 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.
and pedicelPedicel:
The stalk within an inflorescence supporting a single flower or spikelet.
InflorescenceInflorescence:
The flowering structure of a plant (e.g., umbel, spike or panicle).
