Morphology

Pistia + Stratiotes

Both constituents are botanical genus names referring to aquatic plants, so a learner who knows those meanings can infer the phrase denotes an aquatic plant species. However, this is a Latin binomial and relies on taxonomic naming conventions and specialist knowledge to yield the precise referent (water lettuce), so the exact meaning is not fully predictable for a typical B1 learner.

Etymology

Pistia stratiotes gets its name from the plant's look: its leaves form a round cluster, like a small head of lettuce floating on the water. That's why people call it 'water lettuce' and why it often forms mats that can cover ponds.
