A peculiar (in that it is of all the species the only one that is epiphytal) but much the largest flowered species is the _R. Dalhousiae._ It grows, like the orchids, among ferns and moss upon the trunks of, large trees, especially oaks and magnolias, and attains a height of 6 to 8 feet. The flowers are three to seven in a head, and are 3 1/2 to 5 inches long and as much across the mouth, white with an occasional tinge of rose and very fragrant. In size, colour, and fragrance of the blossoms this is the noblest of the genus. It grows out-of-doors in Cornwall and in the greenhouse in other parts of England as a scraggy bush 10 to 12 feet high. _R. barbatum_ is a tree from 40 to 60 feet high, producing flowers of a rich scarlet or blood-colour, and sometimes puce or rich pink. It is one of the most beautiful of the Himalayan rhododendrons, and is now very common in England, growing freely out-of-doors. Another truly superb plant is _R. Maddeni,_ with very handsome pure white flowers 3 1/2 to 4 inches long and as much across the mouth. This is now a special favourite in England. It grows in large bushes in the open in Cornwall and is very sweet-scented. _R. virgatum_ is a beautiful delicately white-flowered shrub. And _R. campylo-carpum_ displays masses of exquisite pale yellow bells of rarest delicacy. Besides rhododendrons, ash, walnut, and maple become more abundant as we ascend, and at 9,000 feet larch appears, and there are woods of a spruce resembling the Norwegian spruce in general appearance. Among the plants are wood-sorrel, bramble, nut, spiraea, and various other South European and North American genera. The climate is no longer stifling and the leeches have disappeared. We miss many beauties of the tropical forest. But, with the vegetation more and more resembling what we are accustomed to in Europe, we are feeling more at home. The path winds through cool and pleasant woods, following the varying contour of the mountain-sides. We are no longer oppressed by the strangeness of the life around us. At almost every turn we come across something new yet not wholly unfamiliar. And standing out especially in our memory of this region will be the sight of a gigantic lily rearing itself ten feet high in the forest, and as pure in its perfect whiteness as if it had been grown in a garden. It is the _Lilium giganteum,_ and it has fourteen flowers on a single stalk and each 4 1/2 inches long and the same across.
