Summary

Drosera anglica Huds. is of hybrid, amphiploid origin (Drosera linearis Goldie and D. rotundifolia L. being the parents) and generally is not difficult to identify in its largely circumboreal distribution. However, in the northern Great Lakes region of North America where D. anglica occurs sporadically with D. linearis and D. rotundifolia, problems occur when hybrids (D. × anglica) and the true species may be sympatric. Furthermore, there is evidence that amphiploidy and therefore speciation is ongoing in the area. A discussion of the origin of D. anglica, some ecologic factors, problems with identification, and finally suggestions for distinguishing between the species and hybrid is presented.
