N. tetragona of Michigan Flora.
Thus far known in Michigan only from a stream at the head of Duncan Bay, Isle Royale (Veirs in 1963, MICH, IRP), but to be sought elsewhere in the Lake Superior region. A circumpolar species, described originally from Siberia, N. leibergii barely enters the northern United States.
