basal part of the awn
The term '
basal part of the
awn' refers to the lower part of an
awn that differs distinctly from the upper part (e. g. in Poaceae – Grass
family with a
geniculate awn like
Arrhenatherum – Oatgrass). In many Poaceae – Grasses with
geniculate awns the
basal part of the
awn is twisted (e. g. in
Arrhenatherum – Oatgrass).
