Abstract: In this paper, the floral morphology and leaf size of Rhododendron feddei were described and supplemented. Inflorescence subapical, usually 5-flowered; calyx reduced to an undulate rim, glabrous; corolla funnelform 5, corolla tube cylindrical; tube ca. 1.2 cm, tapering narrow toward base; tamens 10, slender, exserted twice longer than corolla, filaments glabrous. This species was similar to Rhododendron stamineum, but it was easily distinguished due to the stiff bristles in midvein of the leaf back midrib. This paper provided some valuable information for further taxonomic revision of Rhododendron species.
