Notes: Recently published (2017) as a North American segregate of the Eurasian Botrychium lunaria. The Botrychium lunaria species complex has in recent years been split up into a number of named species, represented in Washington by Botrychium crenulatum and Botrychium neolunaria. Botrychium neolunaria is a diploid taxon and one of the parents of the allotetraploid Botrychium minganense, with which it is often confused in our area.
