A genus of grasses commonly known as crabgrass, having finger-like seed heads.
From Latin 'digitus' (finger) plus '-aria,' a suffix forming scientific names, referring to the grass's characteristic finger-like leaf arrangement or seed structure.
Digitaria is the scientific name for crabgrass, named 'finger grass' because the leaves spread out like fingers on a hand—it's the same 'digit' origin as digitalis, but applied to grass instead of flowers.
