In Emmet and Cheboygan counties, Michigan, differing habitat preferences between the two varieties of Maianthemum canadense do not seem to exist. Some morphological differences cited by former workers were verified. Blooming time varied widely in both varieties, and this variation directly influenced the formation of intermediates. These putative hybrids were found when overlap in blooming periods occurred. When the varieties bloomed at distinctly different times, very few intermediates were present. Because of the widely differing degrees of pubescence shown by the putative hybrids, introgressive hybridization was suggested, but not adequately demonstrated.
