|discussion=<p>First collected as a rice field weed in Butte County, California, in 1944 (C. V. Morton and J. T. Howell 1945), <i>Dopatrium junceum</i> has spread across similar habitats in the Sacramento Valley (S. C. H. Barrett and D. E. Seaman 1980) and in Louisiana (J. W. Thieret and D. H. Dike 1969). <i>Dopatrium junceum</i> germinates in inundated wetlands in May and blooms during summer, which suggests that, at least in California, it is unlikely to spread to vernal pools and other seasonal wetlands that are inundated only during the winter rainy season.</p>
