Parnassia palustris
Species of flowering plant in the family Celastraceae
Parnassia palustris, the marsh grass of Parnassus, northern grass-of-Parnassus, or just grass-of-Parnassus,[2] and bog star,[3] is a flowering plant in the staff-vine family Celastraceae.[4]
It is the county flower of Cumberland in England, and appears on its flag.[5]
The name comes from ancient Greece: evidently the cattle on Mount Parnassus appreciated the plant; hence it was an "honorary grass".[6] The specific epithet palustris is Latin for "of the marsh" and indicates its common habitat.[7] It was described by the Greek physician Dioscorides, growing up a mountain in 1st century A.D.[8]
