Did you know?
The specific epithet sychnocephala means many headed (Fernald 1970). While this species has 3-8 spikes this is not "many" compared to other closely related species.

State Ranking Justification [-]
There are no known populations and only six historical populations. This was last collected from New York in 1935. New York is this species' southeastern range limit.
