The very handsome Primula here described is one 
of the discoveries of Mr. G. Forrest, by whom it was 
first collected in July, 1913, on the Chungtien plateau 
in Yunnan, 27° 55’ N. Lat., at about 12,000 to 13,000 
feet above sea-level, where it grows in open Alpine 
meadows. Seeds of P. chionantha were presented to 
Kew by Mr. J. C. Williams, of Caerhays Castle, Cornwall, 
in April, 1915, from the fruits of Mr. Forrest’s collection 
of 1914 on the Mekong-Salwin divide, also in Yunnan. - 
i were raised and planted in the Rock Garden 
at Kew, where they flowered in May, 1917, when our 
figure was prepared. The species has proved perfectly 
hardy at Kew, but, like all those belonging to the same 
JuLy-SEPTEMBER, 1919.
