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 has large underground roots that look like potatoes and were often cooked as food by Aboriginal people. So the name links the 'potato' look of the root to the 'fern' plant.
