Dichanthelium leibergii
Also called Leiberg's Millet, Leiberg's Panicgrass, Leiberg's Rosette Grass, Leiberg's Panic Grass, Leiberg's Witchgrass, Prairie Panic Grass
Dichanthelium leibergii, known as variously as Leiberg's panicum, Leiberg's panicgrass, Leiberg's rosette grass, and prairie panic grass is a species of grass native to North America. It was named after John Bernhard Leiberg (1853-1913), a Swedish-born American botanist active in the western United States who described the species in 1889.
Dichanthelium leibergii ranges north to Alberta, west to Kansas, and east to New York state. Although it is "fairly common" in Manitoba and it was formerly a dominant species in mesic to dry tallgrass prairies in Iowa, Wisconsin, and Minnesota, it is now a rare species across much of its range. In most surviving prairies and oak savannas, it has decreased in abundance, likely because of fire exclusion and late-spring fire, which favor big bluestem and indiangrass because of their long rhizomes that let them emerge through litter and the belowground buds along their rhizomes that permit them to resprout when their culms or rhizome tips are damaged by fire. It is state threatened in Indiana, Michigan, and Ohio and state endangered in New York. It is extirpated in Pennsylvania.
