Morphology

horned + pondweed

The phrase is a straightforward adjective+noun describing a pondweed that has horn-like structures: the meaning is directly derivable from 'horned' (having horns) + 'pondweed' (an aquatic aquatic plant). This is a compositional, descriptive compound following regular English morphology, so a B1 learner who knows both constituents would readily understand the referent.

Etymology

Horned pondweed may come from its small, horn-like seed pods or leaf tips and the word pondweed, which means a 'weed' that grows in a 'pond'. So the name helps you picture a water plant with tiny 'horns' that lives in ponds and aquariums.
