Rhododendron gratum T. L. Ming, Acta Bot. Yunnan. 3: 118. 1981.

Leaf blade usually elliptic; abaxial surface indumentum usually discontinuous, transparent or translucent, sometimes quickly lost. Corolla without color flecks. Fl. Apr–May.

Rhododendron thickets; ca. 3200 m. W Yunnan.

Field observations at the type locality suggest that subsp. gratum is a form of Rhododendron basilicum with only slightly winged petioles; this fits reasonably well with the distribution of the latter species.
