      I like that you included terminology similar to the Hulten Key. I tried to do that as well when creating my own. Your dichotomous key allowed me to work through the 4 samples very easily. I also like that you did not include color as a primary or single identifier as some plants can vary in color and can prevent us from identifying correctly. I’m curious about including more than one identifier in a step if we were dealing with a single plant in the field and were trying to make a specific identification. This was something I struggled with when creating my own. I found the assignment challenging because I kept thinking about actually including enough steps/branches to identify a plants genus and species (as we would do in the field), but I did think we could differentiate the 4 plants quite quickly into main groups as they had such different features.
