This species is readily distinguished by its usually single, zig-zagged or angular, green stem, and also by its broad oval, yellowish green leaves. The latter have short stems and a very strongly and sharply toothed margin, and acutely pointed tips. Sometimes the upper leaves graduate into smooth edged, lance-shaped formations. Otherwise the plant has, in a general way, many of the characteristics of the preceding species, and the light yellow flowers are set quite the same. The prolonged, slender, leafy stem does not seem to be strong enough to hold itself erect, and it is more apt to be found in a reclining or bending position. It prefers the shadows of rich, open, wooded banks from New Brunswick to Georgia, and to Minnesota and Missouri, from late July to early October.
