1. The Chinese Snowball Viburnum, also known as Sweet Viburnum in "Illustrated Pharmacopoeia" and Wax Lotus in "Chinese Tree Classification", is a shrub that grows 2-3 meters tall. Its small branches are cylindrical or slightly rhomboid, covered with white flat hard hairs that turn grayish-brown as they age. The leaves are arranged in pairs; leaf stalks are 1-5cm long; leaf blades are lanceolate, elliptic-lanceolate, or inverted-ovate, 20-30cm long and 2-8cm wide, gradually tapering at the tip, with a wedge-shaped or round base, finely serrated edges with hard tips at the teeth, green on the upper surface, gray on the lower surface, and covered with flat hard hairs on both sides. The flowers are arranged in umbel-like clusters, with flower stalks densely covered with flat hard hairs; the flowers are of two types: the outer flowers are sterile, with 4 sepals that are petal-like, white or purple, broadly oval with serrated tips, about 2-4cm in diameter; the central flowers are fertile, white, with calyx tubes fused with the ovary, sparsely covered with flat hard hairs, triangular sepals, 5 oblong petals arranged in a clasping manner, 10 stamens, 1 pistil, inferior ovary, 2 columnar stigmas. The fruit is a hemispherical capsule, truncate at the apex, about 3mm long, with ridges. The seeds are tiny, with wings at both ends, and yellowish-brown. The flowering period is from May to August, and the fruiting period is from August to September.2. The Umbrella-shaped Snowball Viburnum, also known as Umbrella Flower Eight Immortals in "Tianmu Mountain Medicinal Plants", differs from the Chinese Snowball Viburnum in that its small branches and leaf stalks lack spreading soft hairs. The leaf blades are narrowly elliptic or narrowly oblong, up to 15cm long, and covered with hairs on both sides. The flower clusters are arranged in umbrella-like branching patterns, without a main flower cluster axis. The seeds do not have wings. The flowering and fruiting period is from June to September.
