>By "leaf shape" I meant the general shape of leaf that a tree has, for example oak has a different shaped leaf to sycamore. Anyway, I've decided to withdraw my tree argument because I've decided that the particular shape leaf for a tree is not temporary as even when the tree has no leaves, there is still a genetically coded property about what shaped leaves the tree should have.
