Rhododendron brachyanthum ssp. hypolepidotum

A rather humble plant, but with fine, long-stalked flowers. Hardy in the garden.The leaves are very aromatic.The lower surface of the leaf is glaucous with dimorhic scales. Dark ones are very scattered, ligth ones are more densely spaced (photo).The calyx lobes are pointed on the garden specimen and on a specimen we collected in NW Yunnan in 2016. The calyx lobes are rounded on the holotype and so they are in the description in Flora of China. The calyx lobes on flowers depicted on the web are of both types, thus indicating a natural variation? The subspecies is distributed in SE Tibet, C and W Yunnan and NE Burma at 3000 – 3600 (4000) m according to Flora of China efloras org.
