Morphology
Potamogeton + nodosus
This is a Latin binomial (genus + species) where only the genus element signals an aquatic plant; the species epithet 'nodosus' is not an English lexical item and conveys no transparent meaning to a B1 learner. Understanding that this refers to a particular species requires botanical or Latin knowledge rather than simple composition of familiar English words, so the expression is not derivable from its parts.
Etymology
Potamogeton nodosus may come from old Greek and Latin words: Potamogeton comes from a word for 'river', so it names a water plant, and nodosus is Latin for 'knotty' or 'with nodes'. Those 'nodes' are the places on the stem where its floating leaves grow, so the name fits this pondweed found in calm lakes.
