Morphology

black + tree + fern

This is a literal descriptive compound: 'black' (color) + 'tree' (tree-like, tall) + 'fern' (a type of plant) combine to name a type of fern that is tree-like and dark in color. The meaning follows ordinary adjective + noun composition and is cross-linguistically common, so a B1 learner who knows the constituents can infer the referent.

Etymology

The plant name black tree fern likely comes from how the plant looks: it is a fern that grows like a tree and often has a dark, almost black trunk. So the name came to mean 'a large fern with a dark trunk'.
