Morphology

Azolla + caroliniana

This is a scientific binomial (genus + specific epithet): if a learner knows 'Azolla' as an aquatic fern they get the core referent, but 'caroliniana' is a Latin epithet (not a common English word) and its contribution (likely indicating origin) requires taxonomic knowledge. Because recognising that the two-word Latin name denotes a species and interpreting the epithet is not guaranteed for an average B1 learner, the MWE is only partially predictable.

Etymology

Azolla caroliniana is the scientific name of a tiny water fern. The word Azolla names a group of small, free-floating ferns that often form mats on ponds, and caroliniana means 'from Carolina', so the name helps you remember it is a small pond fern linked to that region.
