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
Yellow to black and mixtures in between
Hairs on pedicelPedicel:
The stalk within an inflorescence supporting a single flower or spikelet.
and 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.

This unit appears very much like Sorghum halepense except that it is somewhat larger. The intact pedicelPedicel:

make it very similar to S. halepense, however.
