The material for the accompanying figure of Rhodo- 
dendron dichroanthum we owe to the courtesy of Mr. J. C. 
Williams, in whose collection at Caerhays it flowered 
in May, 1918. ‘The species is one discovered by Mr. G. 
Forrest in July, 1906, at altitudes of from 9,000 to 
11,000 feet above the sea, in shady situations of the 
open country on the eastern flank of the Tali Range, in 
western Yunnan, in 25° 40'N. Lat. Of two distinct 
gatherings of the species obtained in 1906 Forrest 
describes the corollas as being creamy rose or yellowish 
rose. The plant now figured had, however, purplish-red 
flowers, and Mr. Millais records the corolla of this species 
JuLY-SEPTEMBER, 1919.
