My initial fascination with science (not counting dinosaurs), began with the study of botony and my perceived need to be able to identify any species of tree while passing at 50 mph. However, identifying everything one may find while hiking is a lot more difficult. I've started collecting my plant photos in an interactive plant identification guide that will, if nothing else, help me to know when I've already photographed a specific species.
