| Comments | I've made several observations of frogbit in the black river and in a neighboring watershed in the past two years; this is the most recent record I have. Will submit other observations. This small impoundment was observed earlier in 2022 to have a larger population in the northeast corner. I will likely submit this as a separate record. I have pressed specimens for some of these populations, please do not hesitate to reach out to me if one of these is desired or if I can provide any additional info. |
