One exception is the picture I'm showing you here. It's an illustration of "subdivision of kingdom Plantae" (that was my brief, the rest was entirely up to me. Told you my brain was expanding.) I could have just done a tree diagram with the names of the various divisions, but then I thought "tree diagram, har har" and made an actual tree diagram, with examples of plants from every division growing out of it. I'm hoping it will help the students to envision the relationships between the plants better than a plain wordy diagram would have done.

The copyright for this diagram is going to be transferred to the Tshwane University of Technology.
