In the month of March, 1853, our first plant of Rhododendron 
glaucum, about a foot high, showed flower-buds, and in the fol- 
lowing month the blossoms were in perfection, as here repre- 
sented. It is an extremely distinct species, reared from seeds 
sent home from the Sikkim Himalaya by Dr. Hooker in the 
autumn of 1850. It inhabits rocky depressed ridges of Sikkim 
and Bhotan, at elevations of from 10,000 to 12,000 feet above 
the level of the sea. Our flowering plant had the protection 
of a cool greenhouse; others in the open border thrive well, 
but have not yet blossomed. In its native country the flower- 
ing season is May. ‘The leaves have often a scurfy character 
from copious small scales, less abundant in the oldest leaves, 
and fewer on the underside of the leaf than on the upper 
and darker. Similar peltate and orbicular scales exist on the 
branches, pedicels, and on the very large calyx. The corollas, 
rose-coloured and really handsome, are rather glandular than 
scaly. Dr. Hooker’s figure is very beautiful and correct in 
~ the — above quoted. The whole plant has a strongly resinous 
smell.
