Abstract:

Botrychium michiganense W.H. Wagner ex A.V. Gilman, Farrar & Zika is described as a new moonwort species. It is an allotetraploid, most likely descended from hybrids between ancestral B. lanceolatum s.l. and B. pallidum. It has a pinnate to pinnate-pinnatifid trophophore (sterile segment) and is most similar to B. hesperium and B. matricariifolium. These three species can be distinguished by trophophore shape and dissection and B. michiganense is genetically distinct from the others as evidenced by different allozyme profiles. Botrychium michiganense ranges from New Brunswick, the St. Lawrence region of Quebec, the Great Lakes region of the US and Canada, the Black Hills of South Dakota, and west through the Rocky Mountains to eastern British Columbia and Washington.
