Notes: Rhododendron lapponicum subsp. alpinum reaches west to Kharaulakh and at least east to the Yukon Territory. The relationship between subsp. alpinum and subsp. parvifolium remains to be clarified. Malyschev (1997) synonymized subsp. alpinum with R. lapponicum s. str., not with subsp. parvifolium, but did not report R. lapponicum s. str. from Dahuria from where "alpinum" was described.
