--><p>As many as 10 Eurasian species of <i>Trollius</i> have been cultivated in North America as ornamentals. Of these, only T. europaeus Linnaeus has been reported to escape. The species infrequently persists near old dwellings in New Brunswick (B.Boivin 1966; H.Hinds, pers. comm.). <i>Trollius</i> europaeus may be distinguished from all North American species by its globose flowers with strongly incurved sepals (in North American species flowers are shallowly bowl-shaped with sepals ± spreading).</p>
