Now, too, we have reached the habitat of the rhododendrons, which are so peculiarly a glory of Sikkim, and it is worth while to pause and take special note of them. Out of the thirty species which are found in Sikkim, all the most beautiful have been introduced --chiefly by Sir Joseph Hooker--into England, and are grown in many parks and gardens as well as at Kew. So English people can form some idea of what the flowering trees of the Sikkim Forest are like. But they must multiply by many times the few specimens they see in an English park or hot-house, and must realise that as cowslips are in a grassy meadow, so are these rhododendron trees in the Sikkim Forest. Red, mauve, white, or yellow, they grow as great flowers among the green giants of the forest and brighten it with colour. The separate blossoms of a rhododendron tree cannot compare in beauty with the individual orchid. There is in them neither the deep richness of colour nor wonder of form nor sense of deeply matured excellence. The claim of the rhododendron to favour is rather in the collective quantity and mass of flowers so that by sheer weight of numbers it can produce its effect of colour. In some of the upper valleys the mountain slopes are clothed in a deep green mantle glowing with bells of scarlet, white, or yellow. Perhaps the most splendid of these rhododendrons is _Rhododendron grande_ or _argenteum,_ which grows to a height of from 30 to 40 feet, and has waxy bell-shaped flowers of a yellowish-white suffused with pink, 2 to 3 inches long and about the same across. The scarlet _R. arboreum,_ so general in the Himalaya, is common in Sikkim and furnishes brilliant patches of colour in the forest. And a magnificent species is _R. Auchlandii_ or _Griffithianum,_ which has large white flowers tinged with pink, of a firm fleshy texture and with a mouth 5 inches across. It has been called the queen of all flowering shrubs. It grows well in Cornwall, and among the hybrids from it is the famous Pink Pearl. _R. Falconeri,_ a white-flowered species, is eminently characteristic of the genus in habit, place of growth and locality, never occurring below 10,000 feet. In foliage it is incomparably the finest. It throws out one or two trunks clean and smooth, 30 feet or so high, the branches terminated by immense leaves, deep green above edged with yellow and ruby red-brown below. The creamy white flowers are shaded with lilac and are slightly scented. They are produced in tightly-packed clusters 9 to 15 inches across and twenty or more in numbers.
