Morphology
Although 'brake' (a patch or growth of ferns) gives a clue that the phrase relates to ferns, the compound 'canker brake' is a lexicalized botanical name and 'canker' (a disease) does not transparently describe the species' evergreen pinnate leaves. A B1 learner who knows both constituents would likely misinterpret it (e.g. as a diseased fern) or fail to derive the specific botanical meaning, so the expression is not predictable from its parts.
Etymology
Canker brake may come from old words: brake once meant 'fern' and canker meant a 'sore' or plant 'disease'. So the name gives the image of a fern with spots or damage, which is why it refers to a type of fern today.
