Waxy Meadow Rue (Thalictrum revolutum)
Also called Skunk Meadow Rue, the name it bears in the Flora of Virginia.
Ranunculaceae or Buttercup Family

Plant 2 to 6 feet tall, with an open spreading inflorescence. Leaves are divided into multiple leaflets, which usually are  oval with three large lobes at the tip.  Leaflets have waxy grains underneath which smell somewhat skunky.  Male and female flowers are usually on separate plants.  Male flowers  (top row and middle row, left) have wide-spreading white to greenish sepals but no petals.  The flowers droop and the yellow to brown pollen-producing anthers hang below on white stalks.  Female flowers (middle row, right and center) point in various directions.  They, too, have wide-spreading, white to green sepals and no petals. The pollen-catching stigmas are white, turning brown, at the tips of tiny green bulbs which will develop into fruit.   Plant blooms in early summer in woods and on ledges.

Common on the low ledges along Wildwood Drive under the powerline, and also spreading into the woods on the east side.

Early meadow rue blooms earlier, often in shadier places.  It has similar flowers, except they are greenish and have both male and female parts.  Leaves are distinctly different, with scalloped edges.
