Morphology
This phrase is fully compositional: 'genus' names a biological rank and 'Arum' is the name of a plant genus, so 'genus Arum' straightforwardly denotes the genus called Arum. Taxonomic noun‑noun constructions like this are regular and cross‑linguistically transparent, so a B1 learner who knows both constituents can infer the meaning.
Etymology
Genus Arum takes its name from an old Greek and Latin plant word 'aron' for the wild arum, a woodland plant with thick, potato-like roots, big heart-shaped leaves and a strange hooded flower. So genus Arum simply means the scientific group named after that familiar plant, remembered for its roots and showy leaves.
