Abstract: The new genus Sinopora J. Li, N. H. Xia & H. W. Li is reported for the Lauraceae from Hong Kong in South China and is based on Syndiclis hongkongensis N. H. Xia, Y. F. Deng & K. L. Yip. The new genus is distinguished from Syndiclis Hooker f. by its trimerous flowers. The new genus is similar to Hexapora Hooker f., but its anthers are originally introrse and tubular, with two anther cells near each other and apically opening by minute pores, the staminodes as large as the stamens, but not produced above the stamens.
