Species
Isopyrum stipitatum (syn. Enemion stipitatum ) is a species of flowering plant in the buttercup family known by the common name Siskiyou false rue anemone. It is native to northern California and southern Oregon where it grows in forest, woodland, and chaparral habitats in the local mountain ranges. This is a petite perennial herb producing one or more erect, unbranched stems to a maximum height no more than 15 centimeters. Leaves appear toward the top of each stem in arrays of several cloverlike leaves with three-lobed leaflets. The tiny solitary flowers each have five white petallike sepals only a few millimeters long. The center of the flower contains several thick white stamens topped with small yellow anthers and 3 to 5 styles.

This is a small perennial herb producing one or more erect, unbranched stems growing to maximum heights near 25 centimeters. Leaves appear toward the top of the smooth, naked stems. Each green cloverlike leaf is divided into usually three irregular lobes. The solitary flowers are petite with white to very light lavender petallike sepals and no petals.
