foxtail barley
FascicleFascicle:
Much the same as a burr except the spikelet glumes are soft, e.g. buffelgrass.
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.
, cluster of three
Light brown
Flat surfaces smooth; awnsAwn:
A narrow, bristle-like organ, as on the glumes or lemmas of grasses (Poaceae).
, glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it.
, and margins scabrousScabrous:
Rough to the touch, covered with minute points of very short, stiff hairs.
.
Broadest in middle with straight taper to either end; awned.
Broad and flat
Two pedicellate, sterile 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. on either side of the fertile one
The unit disarticulates with a segment of the rachisRachis:
The central axis of an inflorescence.
. Two lateral 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. are pedicellate with linear glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it. and a rudimentary floretFloret:
A small flower in a clustered inflorescence (e.g., sunflower, grasses). In grasses, a floret consists of the lemma, palea, stamens, and pistil.
. The central, fertile floretFloret:
A small flower in a clustered inflorescence (e.g., sunflower, grasses). In grasses, a floret consists of the lemma, palea, stamens, and pistil. is sessileSessile:
A flower or spikelet with no pedicel therefore attached directly to the central axis (rachis) or other surfaces.
