  1. Thanks Alexis,
    nice key. Really once you get to B. flowers have petals, there is not need to for the C an C’ statements, since there is no plant with less than 4 petals, so you could just use your D and D’ statements instead to separate plant 2 from plant 3 immediately after B. Flowers have petals – C.
