The climbing plants were still _Panax_ or _Aralia, Kadsura, Saurauja, Hydrangea,_ Vines, _Smilax, Ampelopsis, Polygona,_ and, most beautiful of all, _Stauntonia,_ with pendulous racemes of lilac blossoms. Epiphytes were rarer, still I found white and purple _Cæloynes,_ and other Orchids, and a most noble white Rhododendron, whose truly enormous and delicious lemon-scented blossoms strewed the ground. The trees were one half oaks, one quarter Magnolias, and nearly another quarter laurels, amongst which grew Himalayan kinds of birch, alder, maple, holly, bird-cherry, common cherry, and apple. The absence of _Leguminosæ_ was most remarkable, and the most prominent botanical feature in the vegetation of this region: it is too high for the tropical tribes of the warmer elevations, too low for the Alpines, and probably too moist for those of temperate regions; cool, equable, humid climates being generally unfavourable to that order. Clematis was rare, and other _Ranunculaceæ_ still more so. _Cruciferæ_ were absent, and, what was still more remarkable, I found very few native species of grasses. Both _Poa annua_ and white Dutch clover flourished where accidentally disseminated, but only in artificially cleared spots. Of ferns I collected about sixty species, chiefly of temperate genera. The supremacy of this temperate region consists in the infinite number of forest trees, in the absence (in the usual proportion, at any rate) of such common orders as _Compositæ, Leguminosæ, Cruciferæ,_ and _Ranunculaceæ,_ and of Grasses amongst Monocotyledons, and in the predominance of the rarer and more local families, as those of Rhododendron, Camellia, Magnolia, Ivy, Cornel, Honeysuckle, Hydrangea, Begonia, and Epiphytic orchids. From Pacheem, the road runs in a northerly direction to Dorjiling, still along the Balasun valley, till the saddle of the great mountain Sinchul is crossed. This is narrow, stretching east and west, and from it a spur projects northwards for five or six miles, amongst the many mountains still intervening between it and the snows. This saddle (alt. 7,400 feet) crossed, one is fairly amongst the mountains: the plains behind are cut off by it; and in front, the snows may be seen when the weather is propitious. The valleys on this side of the mountain run northwards, and discharge their streams into great rivers, which, coming from the snow, wind amongst the hills, and debouche into the Teesta, to the east, where it divides Sikkim from Bhotan.
