Morphology
The phrase combines 'form' (type/shape) with 'genus' (a biological rank), so a learner who knows both words can infer it refers to a genus defined by form rather than natural relationships. However, the specialized taxonomic nuance—that it is an artificial grouping often used for fossils when true relationships are unclear—is technical and not fully predictable from the parts for a B1 learner.
Etymology
Form genus comes from the idea of grouping things by their form, meaning their shape, when scientists cannot place them in a known genus. So it means a 'temporary category' used for fossils or organisms whose relationships are unclear.
