This species was reported for BC by Douglas et al. (2002), however lacked precise location information. It has since been rediscovered in the province by Curtis Bjork in the Nicola Basin, who found it "in three small, highly disturbed vernal pools in grassland and shrub steppe in the uplands between the Nicola River and Quilchena Creek 25-30 km east of Merritt" (Bjork 2008). Associated species are reported as Alopecurus carolinianus, Beckmannia syzigachne, Eleocharis macrostachya, Limosella aquatica, Myosurus minimus, Plagiobothrys leptocladus, Rorippa curvisiliqua, and Veronica peregrina (Bjork 2008).
