Did you know?
The specific epithet typhina refers to cat-tails (Fernald 1970) perhaps due to the resemblance of the spikes of Carex typhina to the spikes of cat-tails (the plant not Whiskers).

State Ranking Justification [-]
There are six known populations but only one has more than a hundred plants. Twenty-two historical locations need additional surveys. One may jump to the conclusion that this sedge is overlooked, however, it appears to be rare throughout the northeastern U.S. and adjacent Canada. This plant is typically found as small populations within wet woods and may be subject to hydrological changes, invasive species, or land-use changes.
