Pine, Pinus, in Chinese, many of them are called `fir`, the general characteristic is a leaf shape like a needle to prevent water from being evaporated. In some places where the climate is not so hot, about more than 40 degrees to 60 degrees north latitude, such as Europe, these plants are also common. Leaves of flat linear or needle shaped, spirally alternate, or clustered on short shoots. Pine needles are the impression of most people on pine trees, and there is a thick layer of cuticle and a coating of wax on the periphery of each pine needle, which reduces the loss of water on the pine tree and the secret of the survival of pine trees in a very dry environment.
