This species has been recorded from Fujian and Zhejiang, but the material from those provinces differs from typical Piper kadsura in having the abaxial leaf surface uniformly hairy and the peduncles much longer, and seems better regarded as a form of Piper wallichii. The epithet is frequently spelled "kadzura," but there does not seem sufficient justification to treat the spelling used in the protologue as an orthographic error. The synonym Piper arboricola C. de Candolle has nearly always been midapplied to material of P. sintenense.
