The question is a bit tricky, as the terminology "division" is not commonly used for non-seed plants. Let's break it down:

* Divisions are a classification system used for plants, similar to "classes" in animal taxonomy.

* Non-seed plants include groups like mosses, ferns, and liverworts.

To answer your question, we need to know what options are being provided. Please give me the list of options, and I can help you determine which one is *not* a group of non-seed plants.
