The
dicot
. The stalk of the plant can reach up to 200 millimeters (8 in), the leaves up to 100 mm (4 in) and the petals can be up to 36 mm (1.4 in) wide. The flower has five white petals with light green venation. There are five three-pronged sterile stamens, each tipped with drop-like false nectaries, which (along with the visual cue of veins) attract pollinating flies and bees.
Some species are often found in wet calcareous habitats with low fertility, low canopy cover, and high plant diversity.[5] Parnassia glauca is considered to be an indicator species of fens in New York State.[6] Such habitats are often becoming rare, and so species of Parnassia may have high conservation value. For example Parnassia palustris is threatened and legally protected in Michigan[7] while Parnassia caroliniana is considered imperiled in North Carolina.[8]
Parnassus flowers are the symbol of the
St. Moluag, the Irish missionary whose staff the clan chiefs hold.[9] Three Grass of Parnassus flowers appear on the Flag of Cumberland, a British county, since that flower grows on Cumberland's lofty fells.[10]
