Question
Hi. We were recently asked to review a site (coastal pond on Cape Cod) for potential Persicaria puritinorum. We did id P.. maculosa on the site, but came across this plant, with smaller leaves and without the visible dark spot in the middle of leaves. With the plants rapidly going into dormancy that could be why they look different. Any help with id on this one is appreciated!
Answer
Dear BlueFlax, good morning. There are some details that I'm unable to see, which means I cannot confidently determine the plants in the image. As best I can see, there are no cilia at the summits of the sheathing stipules. Combined with the inflorescence shape and abundant stipitate glands, it suggests Persicaria lapathifolia. However, I would need a better image of the stipules and tepals to know for certain. I hope this helps.
