Hi, Vaguely related to the discussion on rare plants. Today's Daily Express carries a story about how much various plants have changed over 200 years [1]. It made me wonder about the merits of recording things like leaf sizes on the wiki as a way of identifying plants; perhaps it is a good reason to record such things.
