Morphology
Parthenium + argentatum
This is a Latin binomial (genus + specific epithet) so the structure is compositional: if a learner knew 'Parthenium' as a plant genus and 'argentatum' as related to 'argent-' (silver), they could infer a silvery Parthenium shrub. However, because the name is technical/Latin and does not convey all details (e.g. native range or use as a rubber source), the meaning is only partially predictable to a B1 learner and requires some specialized knowledge.
Etymology
Parthenium argentatum may come from older words that describe the plant. The first part Parthenium was a name for certain plants, and the second part argentatum means 'silver' because the leaves look silvery, so the name helps you remember it is a silvery shrub grown for natural rubber.
