Abstract: Some new discoveries in the taxonomy of the genus Lonicera of Caprifoliaceae in Zhejiang Province were reported. The distribution of two species,L. similis in Zhejiang and L. macrantha in China were respectively excluded. L. guillonii was considerably reinstalled as a species with a new synonym L. macrantha var. heterotricha. Furthermore,L. guillonii var. macranthoides was newly combined. A new species L.sinomacrantha and a new form L. hypoglauca f. pulchra were described. The key to the complex of L. macrantha in Zhejiang was compiled.
