This tissue comes in two main forms. There are still some deciduous trees such as maples and many mosses and ferns resulting in a Jurassic-looking forest. The pointed tips (called drip-tips) channel the water to a point so it runs off - that way the weight of the water doesn't damage the plant, and there's no standing water for fungi and bacteria to grow in. One way to start Buttresses tend to be more prevalent on the windward side of the tree and thus function in tension resistance.
