| Verbatim Directions to Locality: | South of [highway] 20 at intersection of [highway] S-260. |
| Habitat: | South of [highway] 20 at intersection of [highway] S-260. |
| Plant Morphology Observations: | I see no achenes despite the fact the the lvs are very narrow. Fruit set is slight because the anthers of this plant lack pollen. The flowers were a faint pink and there are no plate-like glands on the perianth segments although they are numerous on the leaves. |
| Notes: | Charles B. McDonald - I would be inclined to place this plant with P. hydropiperoides var. hydropiperoides despite the narrow leaves. Brian James Poirier - Plant morphology is from additional tag on specimen authored by Charles Mcdonald.
