A fine, stout plant, about two feet tall, with a thick, spindle-shaped root and dark, rich-green, feathery foliage; the large leaves, over a foot long, appearing smooth but really imperceptibly downy, finely cut and lobed, with long, stout leaf-stalks; the small flowers, yellowish-green or bronze-color, in flat-topped clusters, two or three inches across, with few or no bracts, with tall, stout flower-stalks, and composed of about eighteen, small clusters, forming round knobs, with many bracts, on slender pedicels of various lengths. This grows in rich soil and is conspicuous on account of its size and foliage.
