Rhodoleia is a genus of plants in the family Hamamelidaceae. Together with its sister genus Exbucklandia, Rhodoleia forms the sister clade to the other 25 genera of Hamamelidaceae.[1] Flowers of Rhodoleia are bird-pollinated. Nectar-foraging birds including Japanese white-eyes (Zosterops japonicus, Zosteropidae) and fork-tailed sunbirds (Aethopyga christinae, Nectariniidae), avidly visit the flowers, which they also pollinate in the process.[2]

Species include:

Rhodoleia championii
Rhodoleia henryi
Rhodoleia macrocarpa
Rhodoleia stenopetala
