Morphology
Cyperus + rotundus
This is a Latin binomial name for a specific plant species; the meaning (a perennial sedge with nutlike tubers often considered a weed) is not compositionally predictable from the parts for a B1 learner. Even if a learner recognizes 'Cyperus' as a plant genus, the species epithet and specific properties are not transparently derivable, so the expression functions as an opaque proper name.
Etymology
Cyperus rotundus comes from old words: Cyperus means a kind of 'sedge' and rotundus is a Latin word for 'round', because the plant makes small round tubers underground. That's why the name fits a tough weed with small, nutlike tubers that are hard to remove.
