Plantago arenaria R. W. Smith

A European species, local along railroads and sandy roadsides, in disturbed ground such as parking lots and dumps, and on shores. The oldest Michigan collection seen is from 1909, as a weed in alfalfa in Alcona Co. No other collections antedate 1928 (Emmet Co.).

The seeds have long been used for their laxative and stabilizing properties; they have a very mucilaginous seed coat when wet, as do those of other species.
