Morphology
The term is taxonomic and compositionally interpretable: 'Alnus' denotes a birch-family tree/shrub (alder) and 'rugosa' is a Latin epithet meaning 'wrinkled', so together they indicate a species of alder with a wrinkled characteristic. However, understanding that this is a scientific binomial and mapping it to the common shrub (speckled alder) requires domain-specific knowledge of botanical naming conventions and may not give a full, everyday sense of the plant to a B1 learner. Because the parts give useful clues but not a fully obvious everyday meaning, it is best classified as semi-transparent.
Etymology
Alnus rugosa comes from Latin plant words. Alnus means 'alder' and rugosa means 'wrinkled' or 'rough', and this describes the shrub's rust-colored down on its shoots, so the name helps you remember how the plant looks.
