Did you know?
The specific epithet atherodes means like an ear of wheat (Fernald 1970). This is probably in reference to the cylindrical fruit clusters which apparently reminded the author of wheat.

State Ranking Justification [-]
There are now over 21 known populations with more being found in Jefferson, St. Lawrence, and Oswego Counties. There are 10 good or excellent occurrences. The speculation is this plant is more common than our current information indicates. More survey work is planned for the St. Lawrence River Valley and eastern Lake Ontario region. As a wetland sedge, this plant may be threatened by certain invasive species, manipulations to the hydrology, and changes in water quality.
