Morphology
The compound 'potato fern' can be directly interpreted as a fern that has potato-like tubers or tuberous swellings (a fern + potato), so its specific botanical sense is derivable from the constituents. This noun-noun descriptive pattern is morphologically transparent and cross-linguistically common, so a B1 learner who knows 'potato' and 'fern' would likely infer the meaning.
Etymology
The plant potato fern is a small fern that grows on tree branches and has tiny tuber-like bumps along its root stem that look like little potatoes. That's why people called it a 'potato fern'—the 'potato' bumps help the plant store food.
