Plant about 2 feet tall.  Blooms in early spring with small  white, yellow-green or purplish flowers in a branching terminal cluster.  There are six waxy sepals and six tiny petals at the base of each sepal.  Leaves are divided into leaflets which are often lobed and sometimes have a few large teeth.  Fruit a blue berry. 

Very common in Wildwood in the woods on the western slope.

Easily recognized in ripe fruit or flower.  When neither are present, the leaves are fairly distinctive, but can be confused with those of the unrelated black cohosh.
