I find dichotomous keys to be incredibly difficult. Hoping to get better at it.

Hello,
I chose your key to comment on for my week 3 assignment.
Using your key, I could ID plants 1-4 -so it worked.
Recommendations: I would use the format:
A. Has flowers – B
A’. Does not have flowers -C
B. Flowers are purple – plant 1
(And so on)
Also, you divided up plant 1 into two separate species (maybe you’re right, but I just called it plant 1).
Your methods of classifying were – overall – similar to mine (needles vs leaves and then flower color).
Thanks!
