RHODODENDRUM ARBOREUM ALBUM. Tab. 123. 
Varens, foliis subtüs ferrugineo-tomentosis ; floribus albis. 
Crescit in monte Sheopore Napaliæ, ad summum ejus cacumen, florens mense Aprilis. 
The stately Rhododendrum arboreum of the mountains of India has been fully described and beautifully figured by the 
late Sir J. E. Smith. I shall therefore on this occasion advert only to two varieties of it with which I am acquainted : 
namely, the White-flowered, which is figured in the accompanying plate, and the Rose-flowered, which was published 
in the Botanical Register, vol. 15. p. 1240. Both are confined to the single mountain Sheopore, among those 
which I had an opportunity of visiting during my sojourn in Nipal, occupying the very summit of it, at an elevation 
of not less than 10,000 feet above the sea. I observed a considerable number of individuals, but it appeared to 
me that those with rose-coloured flowers were by far the most common. They attain the size of very large forest- 
trees, and are noble objects at all times. They blossom simultaneously in April, in which state the beauty of them 
surpasses all description, the ample crown of the trees being entirely covered with bunches of large and elegant 
blossoms. The common red-flowered or parent species is likewise found on the above-mentioned mountain, but it 
is less frequent there than in lower situations, where it blossoms a month earlier, that is in March. 
'There cannot be the slightest doubt that the above-mentioned trees are mere varieties of the common Rhodo- 
dendrum arboreum ; and if it were necessary to adduce proofs of this, in addition to the fact that in every essential 
character they perfectly agree, I should mention that I have actually seen the white- and rose-coloured sorts gra- 
dually change into each other, as well as into the colour of the parent tree. “The only marks of distinction from the 
latter, consist in the more or less brown colour of the lower surface of the leaves, which both varieties have in common, 
and the colour of the flowers, which in our variety is pure white, with a very slight tinge of pale pink on the base of 
two or three of the lobes of the corolla. I am convinced, moreover, that from the great elevation at which the 
varieties are found, they will prove hardy trees in this country; and that even the common Nipal Rhododendrum, 
provided the individuals are derived from mountains not lower than that at which its varieties grow, will also stand 
the climate of England.
