About two hundred end seventy-five of these belong within Polygonum. Scientists have also found distinctly recognizable fossil Polygonums which date from prehistoric ages. Dr. F. H.

While studying collection of Colorado fossil plants in the Geological Tunes et Columbia College, Small discovered a remarkably distinct Polygonum belonging to the subgenus Persicaria.
