feet above the sea. Its nearest ally amongst the Hima- 
layan species is R. glaucum, Hook. f. (Tab. 4721), which 
it closely resembles in many characters, but differs in the 
minute obtuse calyx-lobes. 
The specimen here figured was sent me by Dr. Balfour, 
F.R.G., from the Royal Botanic Gardens, Edinburgh, where 
it flowered in March of the present year. It also flowered 
at about the same time at Kew, and with Messrs. Veitch 
in the Combewood Nurseries. It is perfectly hardy, and 
very sweet-scented.—J.D.H.
