FLORA OF MOUNT RAINIER NATIONAL PARK. 
The Clintonia has three radical elliptical parallel-veined leaves and a 
single terminal flower. Its fruit consists of a blue berry. There are 
three species of the false solomon seal in this region—two species of 
twisted stalk and the ovate trilhum—all of which belong to the 
lily-of-the-valley family. 
The Oregon wood sorrel, Oxalis oregona, is extremely abundant 
and grows with those just mentioned. It has white or pinkish-white 
flowers and leaves of three obcordate leaflets resembling clover. The 
juice of this plant is extremely sour. Visitors frequently refer to it 
as that “cloverlike plant in the woods.” A bishop's cap, Tiarella 
trifoliata, has a delicate raceme of small white flowers and pubescent

trifoliate leaves. This plant extends from sea level to about 2,900 
feet, when its leaves appear gradually to change from their trifoliate 
character to unifoliate. All intermediate forms can be found. When 
the transition is complete it is rechristened Tiarella unifoliata. It 
extends in this form to the terminal moraines of the glaciers or above. 
The forest anemone, Anemone deltoidea (fig. 5), forms beautiful 
spots here and there because of its creeping roots, which tend to 
intertwine and bring the slender stems together. The leaves are 
rhomboid serrate with trifoliate leaflets. The delicate white flowers 
last a long time here in the dense shade. The fruit is not conspic¬ 
uous, like that of its relative, the western anemone (figs. 6, 7, and 8), 
in the grassy meadows.
