The twigs are slender, smooth, shiny, green, turning red in sunny areas, with numerous small pores. The winter buds are conical, blunt at the tip, covered with short soft hairs, usually clustered in 2-3 groups, with leaf buds in the middle and flower buds on the sides. The leaves are long elliptic lanceolate, oval lanceolate, or inverted egg-shaped lanceolate, 7-15 cm long, 2-3.5 cm wide, gradually pointed at the tip, with a wide wedge-shaped base. The upper surface is smooth, while the lower surface has a few short soft hairs or is smooth in the vein axils. The leaf margins are finely serrated or coarsely serrated, with glandular or non-glandular teeth at the tips. The leaf stalk is stout, 1-2 cm long, often with 1 to several glands, sometimes without glands. The flowers are solitary, blooming before the leaves, with a diameter of 2.5-3.5 cm. The flower stalk is very short or almost absent. The calyx tube is bell-shaped, covered with short soft hairs, sometimes hairless, green with red spots. The sepals are ovate to oblong, with rounded tips, covered with short soft hairs. The petals are oblong to broadly egg-shaped, pink, rarely white. There are about 20-30 stamens with crimson anthers. The pistil is nearly equal to or slightly shorter than the stamens. The ovary is covered with short soft hairs. The fruit varies in shape and size, being oval, broadly elliptical, or flattened round, with a diameter of (3)5-7(12) cm. The color changes from light green-white to orange-yellow, often with a red blush on the sunny side. The outer surface is densely covered with short soft hairs, sometimes hairless, with a distinct ventral suture. The fruit flesh can be white, light green-white, yellow, orange-yellow, or red, juicy, fragrant, sweet, or sweet-sour.
