The branches are slightly four-angled with glandular dots, and narrow wings along the edges. There are two types of leaves: normal leaves grow on mature trees, with a leaf stalk about 2cm long, and the blade is sickle-shaped and lanceolate, thick, 12-30cm long, gradually tapering to a long, sometimes slightly tail-like tip, and the base is broadly wedge-shaped and slightly oblique; abnormal leaves grow on young plants and new branches, arranged in pairs, with elliptic-ovate leaf blades, stem-clasping, about 10cm long, short-pointed at the tip, and cordate at the base. Both types of leaves are densely covered with white powder on the underside, giving them a greenish-gray color, and have obvious glandular dots on both sides. It blooms in spring, usually with single flowers in the leaf axils or clustered in 2-3, either stalkless or with extremely short and flat stalks; the petals and sepals form a tubular structure, pale yellowish-white in color, with a diameter of 3cm; numerous stamens are arranged separately.
