Morphology
Triostium + perfoliatum
This is a botanical Latin binomial rather than a compositional English phrase: one element is a genus name and the other ('perfoliatum') is a technical/Latin form not present in the learner dictionary. A B1 learner who knows the listed constituents would not be able to derive the specific botanical sense (a herb with perfoliate leaves) from these parts, so the expression is not transparently interpretable.
Etymology
Triostium perfoliatum may come from Latin parts: tri- meaning 'three' and perfoliatum meaning a leaf the stem looks like it goes 'through'. Picture a stem seeming to pass through big leaves with purple or red flowers nearby— that's why the name helps you remember this coarse, weedy herb with large, perfoliate leaves.
