PhytoKeys 157: 145–153 (2020)

ABSTRACT

Didymocarpus lobulatus, a new species endemic to Zhejiang province, eastern China, is described and illustrated with photographs. The new species is morphologically similar to D. heucherifolius, D. cortusifolius and D. salviiflorus in leaf morphology, but can be easily distinguished by a combination of characters, including the shape of bracts, calyx and calyx lobes.
