Individual flower heads have five small petals, less than half an inch in length, and from 5 to 10 longer white stamens, topped by yellowish anthers. Flower centers have a greenish tint. The plant is relatively common, found in bogs and other moist places in the high mountains of the Pacific and northern Rocky Mountain states. Leaf branches are stout and woody.
