Question
This plant was growing in Mother Brook in Dedham (canal that connects the Charles River with the Neponset). It looks like Elatine sp. based on leaves but the flowers appear brighter yellow than any species located in our region. The two images are from different plants near each other. I assume they are the same species because the area was covered by a carpet of this plant, but I can't be certain. The area is normally below the waterline. I will email image if incorrect one appears.
Answer
Dear stephradner, good morning. Your plant is Portulaca oleracea (common purslane), a non-native weed that can be prolific in some disturbed settings (e.g., agricultural fields).
