 white, and of a good size, with a fringe of white hairs at the base of 

 each petal. Flower-stems rise about 12 to 18 inches from the

P. palustris.—ThQ native " Grass of Parnassus," which grows 

 freely in damp soil. The white flowers, veined greenish, are borne

 plants.

A lovely creeping plant for a damp, sheltered spot. Its clover-
