Morphology

black + gum

This is a straightforward color + noun compound: a gum (resin-producing/eucalyptus) tree described as black or having dark-colored bark. A B1 learner who knows 'black' and the noun sense of 'gum' (gum tree) can reliably infer it refers to a type of gum tree with dark bark, a common and compositional naming pattern cross-linguistically.

Etymology

Black gum may get its name from the tree's dark, almost black bark and the sticky gum that is really 'sap' rising from the wood. That's why the name fits the tall eastern tree with wide branches and bright fall leaves.
