Morphology

American + wall + fern

The noun phrase is fully compositional: 'fern' names the plant, 'wall' describes its typical habitat (growing on walls or rocks), and 'American' indicates geographic association. This literal, descriptive structure follows normal noun-modifier patterns and would be inferable to a B1 learner who knows the constituent words.

Etymology

American wall fern is a plain plant name: American points to where it comes from, and wall + fern gives the picture of a fern clinging to rocks or old walls. So the name helps you remember that this fern 'comes from America' and often 'grows on walls'.
