GENERIC CHARACTER e 
SPECIFIC CHARACTER | see above. 
Plants of this extremely beautiful species were introduced in 1857 to the gardens of his Grace 
the Duke of Devonshire, at Chatsworth, by Mr J. Gibson, who found it on the summit of the 
Khoseea Hills, in the East Indies, at an elevation of upwards of four thousand feet above the sea. 
Being a plant of unquestionable ped we have selected it to commemorate the services of the 
individual by whom it was collec 
t has been so well depicted s our artist in the annexed drawing, that any remarks on its 
beauty are rendered unnecessary. What, however, gives it a very high claim to distinction, is the 
peculiar fragrance of its blossoms dudar the whole of the time they are expanded, an the very 
agreeable nature of this odour. In this respect it is a most valuable addition to the genus, and will 
furnish an admirable opportunity for improving some of the dark-flowered varieties. 
The habit and foliage of the plant are quite novel among Rhododendrons, and approximate much 
more nearly to those of some Azaleas. This will espeeially be seen in the young lateral shoots exhi- 
bited in the figure, where the form, disposition, and hairiness of the leaves very much resemble 
the same features in most of the Indian Azaleas. The flowers, nevertheless, are decidedly those of 
a Rhododendron, and for their size, delicacy of tint, and the fine yellow spotting in the upper 
portion are alnioat without a rival. 
Mr Gibson discovered it on the side of the mountain, growing in thickets. The À. arboreum was 
in which it flourishes is b e dE Re of loose granite and sandy loam, and is generally 
much interspersed with masse 2 
In England it thrives well in die soil ordinarily used for greenhouse Rhododendrons, which 
consists, for the most part, of loose sandy loam, with the addition of about a third or a age 
of ech heath-mould. The roots of Rhododendrons will not endure to great and exposure 
solar light and heat in the summer, and hence, if they are not in some degree shaded, the udis 
soil; and it may poeni be propagated by grafting on the common sorts. 
Rh ododendron is taken from Rhodon, a rose, and dendron, a tree, in reference to the large 
elusters of rosy flowers which many of the species bear.
