Morphology
The phrase simply combines a known plant name 'arrowroot' with 'family' in the sense of a scientific grouping, so the meaning 'the taxonomic group of plants related to arrowroot' is directly derivable from the parts. This noun+noun compositional pattern is common in English and cross-linguistically, so a B1 learner who knows both constituents should understand it.
Etymology
The name arrowroot family may come from a story about the plant arrowroot, which people long ago used on arrow wounds because its soft, starchy root seemed to help heal them. So today arrowroot family means a 'family' of plants with similar starchy roots, including arrowroot and its close relatives.
