There are a few kinds of Atragene, resembling Clematis. This is peculiarly attractive, as the flowers are large and beautiful and the foliage very pretty. The leaves are divided into three, pointed leaflets, which are thin in texture, light bright-green and prettily cut or lobed, and the trailing or climbing stems are almost smooth, slender and purplish above and woody below. The flowers, which are not in clusters, measure from two to three inches across, with four, sometimes five, violet or blue sepals, spreading widely as the flower grows older, and the outer stamens are broad and resemble small petals. The flowers are followed by handsome feathery heads, which are large and silky. This pretty vine is found in the Grand Canyon, not far below the Rim, and in many mountain places. The foliage varies somewhat in different climates.
There are many kinds of Thalictrum, not easily distinguished, widely distributed, a few in the Andes, India, and Africa; perennials, with tall stems, from a short root-stock, and handsome, compound leaves; the flowers perfect or imperfect, many, small, in clusters, with four to seven s.-pals and no petals; the akenes tipped with the long styles and forming a head. Some of these plants have a disagreeable smell. They grow in moist places, both East and West.
