The charming Rhododendron here figured was first met 
with by Mr. G. Forrest on the western flank of the Shweli- 
Salwin divide in south-western Yunnan in August, 1912, 
at elevations of about 10,000 feet and was found again 
by the same collector at similar elevations on open 
rocky slopes in the following June. Described at 
Edinburgh from specimens of the second gathering, 
R. callimorphum is now in cultivation in various collec- 
tions in this country and appears to be fairly hardy at 
Caerhays Castle in Cornwall, whence Mr. J. C. Williams, 
with whom alone it has yet flowered, supplied the 
material for our plate ; also at the Sunningdale Nurseries
