Grass of Parnassus (Parnassia palustris) a local species found in damp grassy places and in marshes, usually in mountian regions in mainland Europe. The name comes from ancient Greece: evidently the cattle on Mount Parnassus appreciated the plant; hence it was an "honorary grass". The species epithet palustris is Latin for "of the marsh" and indicates its common habitat. It was described by the Greek physician Dioscorides, growing up a mountain in 1st century AD.
