Abstract
Beilschmiedia weii, a new species of Lauraceae from Dayaoshan Mountain of Guangxi, China, is described and illustrated. It is morphologically most similar to B. wangii and B. rufohirtella in having ferruginous pubescent terminal buds, branchlets, abaxial leaf blades, panicles and fruiting pedicels, but can be easily distinguished from them by the leaf growth pattern, the color of flowers, the length of panicles and fruiting pedicels, the shape and size of fruits, and the phenology. A table to distinguish the new species from other morphologically similar Beilschmiedia species is provided, as well as a color plate.
