Grass of Parnassus

Grass of Parnassus is the English name for the genus Parnassia, also known as Bog-stars. Parnassia is considered by many authors the only genus in the family Parnassiaceae, while others also include the small genus Lepuropetalon. The plants occur in arctic and alpine habitats, as well as in dune systems and bogs, across the Northern Hemisphere.
