The Dutch, in like manner, maintained, during the entire period of their rule, an extensive commerce in pepper worts, which still festoon the forest, but the export has almost ceased from Ceylon. Along with these the trunks of the larger trees are profusely covered with other delicate creepers, chiefly Convolvuli and Ipomoeas; and the pitcher-plant (Nepenthes distillatoria) lures the passer-by to halt and conjecture the probable uses of the curious mechanism, by means of which it distils a quantity of limpid fluid into the vegetable vases at the extremity of its leaves. The Orchideae suspend their pendulous flowers from the angles of branches, whilst the bare roots and the lower part of the stem are occasionally covered with fungi of the most gaudy colours, bright red, yellow, and purple.
Of the east side of the island the botany has never yet been examined by any scientific resident, but the productions of the hill country have been largely explored, and present features altogether distinct from those of the plains. For the first two or three thousand feet the dissimilarity is less perceptible to an unscientific eye, but as we ascend, the difference becomes apparent in the larger size of the leaves, and the nearly uniform colour of the foliage, except where the scarlet shoots of the ironwood tree (Mesua ferrea) seem, like flowers in their blood-red hue. Here the broad leaves of the wild plantains (Musa textilis) penetrate the soil among the broken rocks; and in moist spots the graceful bamboo flourishes in groups, whose feathery foliage waves like the plumes of the ostrich.[1] It is at these elevations that the sameness of the scenery is diversified by the grassy patenas before alluded to[2], which, in their aspect, though not their extent, may be called the Savannahs of Ceylon. Here peaches, cherries, and other European fruit trees, grow freely; but they become evergreens in this summer climate, and, exhausted by perennial excitement, and deprived of their winter repose, they refuse to ripen their fruit.[3] A similar failure was discovered in some European vines, which were cultivated at Jaffna; but Mr. Dyke, the government agent, in whose garden they grew, conceiving that the activity of the plants might be equally checked by exposing them to an extreme of warmth, as by subjecting them to cold, tried, with perfect success, the experiment of laying bare the roots in the strongest heat of the sun. The result verified his conjecture. The circulation of the sap was arrested, the vines obtained the needful repose, and the grapes, which before had fallen almost unformed from the tree, are now brought to thorough maturity, though inferior in flavour to those produced at home.[4]
