| American white waterlily is endangered in Saskatchewan because it is known from a single locality. This location represents a western expansion for this species in Canada. Only one record of this species exists in the W. P. Fraser Herbarium from Saskatchewan. It is likely that this species may face danger of extirpation in the province. | |||||||||||||||
