Morphology
The phrase is directly compositional: 'genus' (a biological rank) combined with the name 'Rosa' yields the taxonomic group called Rosa, i.e. the group that includes true roses. This is a standard, cross-linguistic scientific naming pattern, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.
Etymology
Genus Rosa comes from Latin: genus means a 'group' and Rosa is the Latin word for the rose. So it literally means the 'group of roses', which is why scientists use it for the plants that are true roses.
