Rhododendron luciferum may be a distinct species, differing in the shape of the leaves and their loose, very thick, rufous indumentum. Moreover, the taxon has a more easterly distribution. The largely Bhutanese R. flinckii may also be a distinct species, differing in the red, more velutinous leaf indumentum.

Rhododendron lanatum: Brief Summary
provided by wikipedia EN
Rhododendron lanatum (syn. Rhododendron flinckii), the woolly rhododendron, is a species of flowering plant in the family Ericaceae, native to the eastern Himalayas and southeastern Tibet. Occasionally found in commerce, it is a rabbit-tolerant evergreen shrub reaching 3–10 ft (1–3 m). Hardy in USDA zones 7 through 9, it is recommended as a hedge in partly shady situations.
Its young shoots and leaves are covered with a white to tawny velvety wool, giving it its scientific and common names. May flowers are typically sulphur-yellow with maroon-spotted throats, and there is a cream-flowered morph.
