Morphology

Potamogeton + gramineus

This is a Latin binomial (a scientific species name) rather than a compositional English phrase; its parts are not ordinary English vocabulary and 'gramineus' is not defined here. B1 learners generally lack Latin morphological knowledge and would not be able to infer 'grass‑leaved pondweed' from these constituents, so the meaning is not derivable from the parts.

Etymology

Potamogeton gramineus may come from old roots potamo- meaning 'river' and -gramineus meaning 'grass-like'. So the name gives the simple picture of a grass-like plant growing in ponds or slow rivers, which is why it is called 'grass-leaved pondweed'.
