Weed
Columbus grass, almum sorghum
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.
OvateOvate:
Egg-shaped with basal end the broadest.
Yellow to black and mixtures in between
Some hair on pedicels and rachisRachis:
The central axis of an inflorescence.

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.

disarticulate by fracture and others by abscission. This is a characteristic that is between that of S. halepense and S. × drummondii. The size is also intermediate but natural variation puts individual units into larger and smaller species. The caryopsisCaryopsis:
The single-seeded fruit or grain of the grass family (Poaceae); the fruit wall (pericarp) is united with the seed coat (testa).
