smooth crabgrass
FloretFloret:
A small flower in a clustered inflorescence (e.g., sunflower, grasses). In grasses, a floret consists of the lemma, palea, stamens, and pistil.
EllipticElliptic:
Outline of an ellipse; greatest width midway sloping to an equally pointed apex and base.
White glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it.
and a black floretFloret:
A small flower in a clustered inflorescence (e.g., sunflower, grasses). In grasses, a floret consists of the lemma, palea, stamens, and pistil.
GlumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it.: densely pubescentPubescent:
Having hairs.
Fertile lemmaLemma:
One of two bracts of the grass floret; it is located on the side nearest the embryo and opposite the rachilla.
: longitudinal striations.
Hard, ellipticElliptic:
Outline of an ellipse; greatest width midway sloping to an equally pointed apex and base., convex
Hard, ellipticElliptic:
Outline of an ellipse; greatest width midway sloping to an equally pointed apex and base., flat.
Papery, sterile glumesGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it. are strongly ribbed. The outer glumeGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it. is equal to the fertile lemmaLemma:
One of two bracts of the grass floret; it is located on the side nearest the embryo and opposite the rachilla..
This unit is strange. The first and lowest structure should be the first glumeGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it., but it is absent. The second is the second glumeGlume:
The pair of chaffy bracts that occur at the base of a grass spikelet, often completely enclosing it., then a sterile and pubescentPubescent:
Having hairs.
lemma that is about equal in length to the 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 fertile lemmaLemma:
One of two bracts of the grass floret; it is located on the side nearest the embryo and opposite the rachilla. is hard, black with fine longitudinal striations.
