The Shield-leaved Raspberry, also known as the Large-leaved Raspberry, is an upright or climbing shrub, reaching a height of 1-2 meters. The branches are reddish-brown or brown, without hair, sparsely covered with thorns, and the small branches often have a white powder. The leaf blades are shield-shaped, ovate-round, measuring 7-17 centimeters in length and 6-15 centimeters in width. The base is heart-shaped, with soft hairs on both sides, denser on the lower side and small thorns along the midvein. The margins are palmately divided into 3-5 lobes, with triangular-ovate lobes that are abruptly pointed or shortly tapering, and irregular fine serrations. The leaf stalk is 4-8 centimeters long, hairless, and with small thorns. The bracts are large, membranous, ovate-lanceolate, measuring 1-1.5 centimeters in length, and hairless. The solitary flowers are terminal, with a diameter of about 5 centimeters or larger. The pedicels are 2.5-4.5 centimeters long, hairless. The bracts are similar to the bracts. The calyx tube is usually hairless. The sepals are ovate-lanceolate, with soft hairs on both sides and often toothed margins. The petals are nearly circular, with a diameter of 1.8-2.5 centimeters, white, longer than the sepals. There are numerous stamens, with filaments either drill-shaped or linear. There are many pistils, up to 100, covered with soft hairs. The fruit is cylindrical or tubular, measuring 3-4.5 centimeters in length, orange-red, and densely covered with soft hairs. The seed has wrinkles. The flowering period is from April to May, and the fruiting period is from June to July.
