The stem's lower part may become somewhat woody, reaching 50-150 centimeters in height, unbranched or with few branches, often forming a zigzag shape in the upper part, with 5 longitudinal ridges, short soft hairs, and sparse prickles, which gradually fall off later. There are 1-3 pearl buds, often growing in the leaf axils without flower clusters, woody, spherical, with a diameter of 3-6 millimeters, and most plants do not have pearl buds. The leaves are ovate to lanceolate, sometimes broadly ovate, measuring (6-)8-16 centimeters in length, (2-5)3.5-8 centimeters in width, gradually pointed at the tip, with a wide wedge-shaped or round base, rarely shallowly cordate, teeth or serrations on the edges from the base upwards, rough appressed hairs and sparse prickles on the upper surface, short soft hairs and sparse prickles on the veins on the lower surface, especially longer prickles on the main veins, glandular dots fine and distinct on the upper surface, 3 primary veins arising from the base, with a pair of slightly curved veins on each side extending to the tooth tip, 4-6 pairs of lateral veins reaching the tooth apex; petioles are 1.5-10 centimeters long, hairy like the upper part of the stem; stipules are oblong-lanceolate, 5-10 millimeters long, with 2 shallow clefts at the tip, rough hairs on the ribs on the back. The inflorescences are unisexual or rarely bisexual, conical, with short soft hairs and sparse prickles on the inflorescence axis; male inflorescences are borne in the leaf axils below the stem apex, with short pedicels, 3-10 centimeters long, branching out; female inflorescences are borne in the leaf axils at or near the stem apex, 10-25 centimeters long, with inflorescence stalks 5-12 centimeters long, shorter branches often attached to one side of the inflorescence axis. Male flowers have short pedicels or are sessile, flattened spherical when in bud, about 1 millimeter in diameter; perianth segments 5, oblong-ovate, concave, without angular projections near the apex on the outside, with slight hairs on the outside; stamens 5; degenerate pistils pear-shaped, about 0.4 millimeters long; bractlets triangular-ovate, about 0.7 millimeters long. Female flowers have pedicels; perianth segments 4, unequal in size, separate, with two larger lateral ones tightly enclosing the ovary, oblong-ovate or narrowly obovate, about 1 millimeter long, later enlarging, somewhat hairy on the outside, one dorsal perianth segment circular-ovate, hood-shaped, about 0.5 millimeters long, one ventral perianth segment the shortest, triangular-ovate, about 0.3 millimeters long; ovary with a pistil, erect, later bent; stigma filiform, 2-4 millimeters long, densely covered with short hairs. The fruit is round-ovate or nearly semicircular, oblique, flat, about 2-3 millimeters long, smooth, with fine purple-brown spots; the pistil extends to about 0.5 millimeters, bending downwards; persistent perianth segments on the side, about 1.5 millimeters long, extending to near the middle of the fruit, somewhat hairy on the outside, sometimes nearly smooth; flower stalks are 2-4 millimeters long, flattened into membranous wings on both sides, sometimes the fruiting branches are also flattened into wings, spoon-shaped, with a deep notch at the tip.
