Parnassia palustris

DE: Sumpf-Herzblatt, Studentenröschen
FR: Parnassie des marais

Parnassia palustris is an evergreen perennial usually flowering from July through August. The flowering stem is terminated by a single, creamy white flower with 5 conspicuously veined petals 8-13 mm long. Alternating with the 5 stamens are 5 staminodia (modified stamens that function to help attract pollinators) divided about halfway to the base into 9 or more distinct filaments. The stamens, which mature before the stigma is fully developed and receptive, ripen and dehisce successively, promoting a longer period for cross-pollination. This species frequently occurs in more alkaline habitats, such as meadows and in damp calcareous sands on lakeshores and dune-slacks.
