Sri Lanka is a land of plenty, for a botanist too! Tropical as well as sub-tropical vegetation survives well. The luxuriant undergrowth, and tall majestic trees are in the wet zone. They contrast with the arid scrub land and talipot palms of the dry north. In the hills, the vegetation varies from almost the tree-less patinas of Orton Plains to the dark cloud forests, wreathed with the protected Old Mans Beard Moss. Flowering orchids and flowers cap the green cover.
