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.
Black
Shiny with hairs at the glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it.
apex
Papery lemmaLemma:
One of two bracts of the grass floret; it is located on the side nearest the embryo and opposite the rachilla.
enclosed in glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it.
Papery paleaPalea:
One of the thin bracts of grass floret enclosing the fruit (caryopsis) that is located on the side opposite the embryo.
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.
and pedicelPedicel:
The stalk within an inflorescence supporting a single flower or spikelet.
attached to the base of the 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..
Characteristics are typical to Sorghum group. The most unique character is the appressedAppressed:
Pressed close or lying flat against something.
hairs at the apexApical:
The distal end of the fruit or seed away from the point of attachment or attachment scar.
of the glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it..
