Discussion

Species 1: North America, Eurasia.

Chamaedaphne has been included in other genera of subfamily Vaccinioideae (Andromeda, Lyonia) and more recently has been placed in tribe Gaultherieae (K. A. Kron et al. 2002). Its leaf anatomy differs from that of other genera in having venation transitional between pleuroplastic and basiplastic types, denser venation, and thin vein endings (K. Lems 1964).
