Grass of Parnassus is not rare but it is uncommon enough to be a pleasant surprise when found.  Tall, delicate, almost leafless stalks are surmounted by brilliant white five-petaled flowers.  Five white stamens alternate with five sterile yellow stamens.  The lower sides of each petal are delicately fringed.  The small, basal, heart-shaped leaves often are folded almost cup-like.  Grass of Parnassus likes subalpine and alpine stream-sides and damp areas.

Linnaeus named this genus in 1753, and Karl D. Koenig named this species in 1804 from a specimen collected by Archibald Menzies in the present day state of Washington in the late 1780s.

"Parnassus" is a famed mountain in Greece sacred to Apollo and the muses, and, according to Intermountain Flora, Dioscorides described a member of this genus he found on the slopes of Mount Parnassus.  He gave it a Greek name which translates as "Grass of Parnassus".  "Fimbriata" means "fringed".

Parnassia parviflora is much less common in the Four Corners area than Parnassia fimbriata and, in fact, the plant pictured is probably the first recorded in Montezuma County, Colorado.  P. parviflora grows from three-to-fourteen inches tall with mostly basal leaves which are often buried, as in this photograph, in a mass of other greenery since P. parviflora typically grows in lush wetlands.  Weber indicates that the plant grows in subalpine wetlands, but this photograph was taken at about 8,000 feet in the flood plain of a small creek.  

This plant is widely distributed around the world, and Linnaeus named this species Parnassia palustris in 1753 from a specimen collected in Europe.  De Candolle renamed it Parnassia parviflora in 1824, and Boivin changed the name to Parnassia palustris variety  parviflora in 1966.  "Parviflora" means "small flowered" and "palustris" means "of the swamps".

Brilliant white flowers attract your attention and then a close examination with a hand lens enthralls you.  Pictured below are several stamens and in between them, several staminodes (non-functional stamens).  They are the yellow hand-like structures with glistening yellow spheres at the end of their finger-like projections.  In the photograph at lower left, the staminodes are encased in rain droplets.
