The species now figured, Rhododendron oreotrephes, 18 & 
native of Yunnan, where it was discovered by Mr. G. 
Forrest on the eastern flank of the Li-Kiang range at 
altitudes of 11,000-12,000 feet, growing in company with 
several other species of Rhododendron, and forming a 
tree fifteen to twenty-five feet high. The material for 
our plate has been received from Mr. J. C. Williams, in 
whose collection at Caerhays Castle, Cornwall, it thrives 
remarkably well, and where, Mr. Williams informs us, it 
is easy to grow if given a fairly exposed situation. It 
bears exposure to the sun at Caerhays better than most 
Rhododendrons, but Mr. Williams has found individual 
plants die very suddenly from no evident cause, and has 
experienced this more frequently with &. oreotrephes 
Ocroper-DEceMBER, 1918.
