Family, Crowfoot. Flowers in compound panicles. Petals, none. Sepals, white. The stamens and pistils are borne on different plants. The staminate flowers are the prettier, in compound panicles, loose and feathery, with white filaments, thicker toward the top. The pistillate flowers are smaller, more compact, and greener. Leaves, thrice compound, cut into fine segments, the leaflets being small, rounded or lobed, oblong, stalked. July to September.
A plant lovely both in its soft, feathery blossoms and its delicate foliage, growing tall, sometimes 8 feet. It masses beautifully with clumps of wild roses wherever the soil is wet and springy. My own observation indicates that the plants bearing staminate flowers are much more common than those bearing pistillate. I have often failed to find one of the latter among many of the former.
