Morphology
hydrilla + verticillata
This is a scientific Latin binomial where 'hydrilla' identifies the plant and 'verticillata' is a Latin adjectival descriptor (from verticillate = 'having whorls'), so the species name is compositionally built from a noun + descriptive element. However, the second constituent is not an English lexical item and is unlikely to be known by an average B1 learner, so understanding the specific sense depends on specialized/botanical or Latin knowledge rather than general vocabulary.
Etymology
Hydrilla verticillata may come from the old Greek word hydor meaning 'water' and the Latin word verticillata meaning 'in a ring'. The plant lives in water and its leaves grow in rings around the stem, so the name points to a 'water' plant with circular leaf groups.
