Parnassia glauca Raf.
Fen grass of Parnassus, Grass-of-Parnassus
Synonym(s): Parnassia americana
USDA Symbol: PAGL3
USDA Native Status: L48 (N), CAN (N)
1 white flower, with petals striped with green veins, atop a stem bearing 1 rounded, clasping leaf at midstem; other leaves basal.
The delicate, green veins of the petals are the distinctive feature of this perennial. Despite its common name, it does not really resemble a grass; Parnassus refers to the Greek mountain, sacred to Apollo, where the ancient naturalist Dioscorides observed similar plants in meadows. Three other very similar species of Parnassia occur in the South.
