Morphology

Lupinus + arboreus

This is a Latin binomial composed of a genus name ('Lupinus' = lupin) plus a species epithet. If a learner knew that 'arboreus' means 'tree-like/arboreal', they could infer it denotes a lupin with a tree/shrub habit, but the full biological details (evergreen, native range, flower colour) are taxonomic facts not predictable from the parts alone. Because the name partly transparently describes a trait but functions as a technical proper name, it is only partially predictable to a B1 learner.

Etymology

Lupinus arboreus gets its name from old Latin words: Lupinus may come from the word 'wolf' because people once thought these plants used up the soil like a wolf, and arboreus means 'tree-like'. So the name creates the image of a woody lupin, which matches the shrubby plant we know today with bright, showy flowers.
