| Comments | The coordinates are from the Dismal Swamp boardwalk were it crosses a slough. They are more or less at the start of the population which runs west. Acreage of coverage is an estimate- the plant may cover much more than 3 acres. Dense monocultures exclude all native herbaceous plants. |
