1. Viburnum sect. Viburnum

裸芽组 luo ya zu

Winter buds naked. Inflorescence a compound umbel-like cyme, without large sterile radiant flowers, pedunculate. Corolla rotate, hypocrateriform or tubular. Fruit initially turning red, maturing black; pyrenes with 2 dorsal grooves and 3 ventral grooves; albumen solid.

About 20 species: mostly in temperate Asia and Europe; 13 species (seven endemic) in China.

This section was divided into three subsections by H. Hara (Ginkgoana 5: 204-213. 1983): Viburnum subsect. Solenolantana (Nakai) H. Hara for V. carlesii, V. subsect. Urceolata Nakai for V. urceolatum, and V. subsect. Viburnum for the remaining species. Recent phylogenetic work shows that V. subsect. Urceolata may be separated from the remainder of V. sect. Viburnum. Viburnum subsect. Lantana and V. subsect. Solenolantana form a monophyletic group, and the recognition of V. subsect. Solenolantana makes V. subsect. Lantana paraphyletic.
