Fruit: Seed: Importance to wildlife: Similar species (if any): Myosoton aquaticum has a resemblance to some Stellaria species, in particular, Stellaria pubera (Star Chickweed), but this species has not been recorded from Wisconsin, Minnesota, and Michigan, but has been observed in more south-eastern states. This latter species has 3 styles, whereas M. aquaticum has 5 styles. The width of the flowers of M. aquaticum can help ditinguish this plant from some of the other Stellaria species, which typically have smaller flower widths.
