   Laura,
   for this exercise, you would just consider all the plants in one plate/ bin to be one plant and the different images in each bin represent different features of each plant, but one bin equals one plant. So when constructing your key you could select one or multiple features of each bin to construct your key. This was meant to be a simple exercise of realizing that you have to organize your data before you can make the key, and that there are different solution to the puzzle. You could start out with dividing the bins up by those with needles, those that are lacking needles, those that have catkins and those that lack catkins, etc. You do not need to account for all the features represented in each of the bins in your key. I hope this makes sense. It looks like you meticulously went through the images trying to incorporate each feature of the plants, but that would really only come into play if all four bins where from the same genus and thus all plants were very similar, but here we were lucky and only had some major categories that allowed us to divide the bins up easily.

   Hello,
   I really enjoyed how detailed your key is! I was easily able to follow your flow. I wish I could have seen your final conclusions for each bin.
