Here’s my Dichotomous Key drawn out in my field sketchbook. It was a bit of challenge for me to think in such a linear way. It seems I like to note the differences in the plants in a bit of a jumble and this exercise kind of forced me to really focus on each difference in their morphology.
A. Species is a tall forest tree with cones…………………………………… plant 1
A’. Species found in forest understory, smaller trees and lacking cones………………………
B. Plants with prominent midrib on the leaves – plant 4
B’ Plants lacking prominent midrib on the leaves- C
C. Species with hairy stems and white petals………………….…………………plant 2
C’. Species with hairy stem, but with lacking white petals.……………………… plant 3
A. Plants with flowers -B
A’. Plants without flowers (Plant 1)
B. Flowers with petals – C
B’. Flower without petals (Plant 4)
C. Flowers with purple petals (Plant 3)

B’. Flower lack petals – Plant 4
C. Less than 4 petals
C’. At least 4 petals – D
D. 4 (white) petals – Plant 2
D’. 6 (purple) petals – Plant 3
A: Without Flowers
B: Tree with pinecones – Plant 1

A1: With flowers
C: Multiple white flowers per stalk – Plant 2
C1: Single purple flower per stalk – Plant 3

I didn’t realize I had such a diverse selection of dishware. Without looking, I suspect there is an artifact key for pottery/dishware since a lot of it shows up in archaeological digs. I know there is a key for beads.
