Did you know?
This prairie grass was first collected in New York in 1832 at the head of Seneca Lake. That was the only collection ever known from the state until 1992 when it was found in a small grassland at Oakwood Cemetery in Troy. The species is named in honor of John B. Leiberg who made many plant collections in the Midwest and Northwest for the US government and the Smithsonian in the late 1800s and early 1900s. His wife Carrie was a doctor who traveled to her patients by railway handcar (Parker 2010).

State Ranking Justification [-]
There is one existing occurrence but it is rather small. There is one historical occurrence from the 1830s that is probably extirpated.
