Parnassia fimbriata is a species of flowering plant in the family Celastraceae known by the common name fringed grass of Parnassus. It was first described by Charles Konig. [3] It is native to western North America from Alaska and northwestern Canada to the southern Rocky Mountains, where it is a plant of alpine and subalpine environments, usually in wet areas. [4] Despite the common name, this is not a true grass.

Description

It is a perennial herb producing an erect flowering stem from a patch of basal leaves. The leaf has a rounded blade at the end of a long petiole, the leaf reaching a total of up to 16 centimeters long. The inflorescence may be up to 40 centimeters tall and consists of a mostly naked peduncle with one clasping bract midway up.

The single flower has five small jagged sepals behind five veined, fringed white petals each roughly a centimeter long. At the center of the flower are five stamens and five staminodes with edges of many narrow, round-tipped lobes.
