Morphology
Eupatorium + rugosum
This is a Latin scientific binomial (genus + specific epithet) whose communicative meaning ('white snakeroot', a toxic herb) is not derivable from the literal constituents for an average B1 learner. The second element 'rugosum' is not a familiar English word and taxonomic names function as arbitrary labels rather than transparent compositional phrases, so learners would not predict the plant’s properties from the parts.
Etymology
Eupatorium rugosum is the formal name for the common wildflower called white snakeroot, and people long ago may have called it 'snakeroot' because of its white flower clusters and a belief it was linked to snakebites. Farmers learned that cows eating it caused 'milk sickness', so the name now points to a dangerous, 'poisonous' plant.
