Bothriochloa bladhii (commonly called, variously, Australian bluestem, Caucasian bluestem, forest-bluegrass, plains bluestem, and purple plume grass) is a neotropic grass in the Poaceae family, found primarily in tropical Africa, and tropical and temperate Asia, and Australia. The type specimen was collected from China by Finnish botanist Peter Johan Bladh. The name of Bladh is honored in the specific epithet.
