New rare trees biome in the overworld.

At the moment, there are only 6 species of trees in Minecraft. They are mostly common and have there respective biomes. I think a new type of tree can be added, this tree could be up to 40 blocks high but in a 1x1 area, and to make it more rare, i think it should not drop saplings. This tree could be found in a new biome which does not spawn hostile mobs that is why is can be called 'Peace Tree'. These trees can be related to wax palms. This can be used for decoration purposes. Maybe it can also give some item that can be used to make paper.
