Morphology
Raphanus + raphanistrum
This is a Latin binomial (scientific name) where the parts are taxonomic labels rather than ordinary English words, and the species epithet 'raphanistrum' is not a transparent English word. A B1 learner who knows the listed constituents would not be able to infer the common-meaning 'wild radish' from these elements without prior exposure, so the expression is not compositional for learners.
Etymology
Raphanus raphanistrum is the scientific name that literally calls this plant a wild radish: Raphanus means radish and raphanistrum shows it grows wild. Imagine small radishes with flowers and seed pods popping up in fields; that's why the name refers to a 'wild radish' that farmers often call a 'weed'.
