Morphology
Psoralea + esculenta
This is a taxonomic binomial (genus + specific epithet) so, in principle, its meaning is compositional: Psoralea (a plant genus) + esculenta (Latin/Latin-derived 'edible') yields 'an edible species of Psoralea'. However, the specific epithet is Latin and not a common English word and the detailed sense given (perennial with tuberous roots) requires botanical knowledge, so a B1 learner who merely knows the surface constituents would only get a general edible-plant sense, not the full specifics.
Etymology
The plant name Psoralea esculenta comes from Latin naming: Psoralea is the plant group and esculenta means 'edible'. Because people on the Great Plains traditionally ate its tuber roots, the name points to a plant that was used as food.
