This genus is synonymous with
Maianthemum
which is now the more commonly accepted name among
taxonomists.
Note:
As people named newly identified plants down through the
centuries, there were often cases where the same plant
was given two or more different names by different
taxonomists. The rule is that the first name that was
publicly displayed in a book or other publication takes
precedence. Once an "accepted name" has been
established, all the other names are then referred to as
synonyms.
