I way over-thought this process, as I initially thought we were to key-out the plants in each bin and develop a dichotomous key for each one. I’m so glad I reviewed the other posts and the instructions again, and hope that this is what we were asked to do: Dichotomous …
A1. Is the plant woody? Bin 1 A2 Is the plant herbaceous? Go to B B1 Does it have a single flower? Bin 3 B2 Does it show inflorescence? Go to C C1 Does it have visible petals? Bin 2 C2 Does it not have visible petals? Bin 4

Hi everyone, I spent the weekend out of range of wifi and cell service, but I’ve got the day off to catch up today. I am really enjoying learning a new vocabulary. I used both the Cody and Hulten keys for keying out the violets. The second violet specimen was …
I was also confused by this assignment, but I believe the intention was to treat this like the lego exercise and devise our own dichotomous key from the bins provided. Here’s mine:
It seems I am not the only one struggling with this assignment.
