Morphology
The meaning is directly compositional: 'iris' (the flower) combined with 'family' (a grouping of related species) yields 'the family of plants that includes irises,' which follows standard taxonomic noun + noun/grouping patterns. This construction is cross-linguistically common and thus a B1 learner who knows both constituents should be able to infer the MWE meaning.
Etymology
Iris family is named after the flower iris, which in turn was linked to Iris, the Greek messenger of the rainbow, because these flowers come in many bright colors. So iris family means a 'group of related plants' such as crocuses and gladioli that share similar colorful blooms and sword-shaped leaves.
