Morphology
The phrase is fully compositional: 'genus' names a biological rank and 'Caltha' is a proper name for that taxon, so the meaning (the taxonomic group called Caltha) is directly derivable from the constituents. This follows standard scientific naming patterns found across languages, so a B1 learner who knows both words would understand the MWE.
Etymology
Genus Caltha may come from an old Greek word 'káltha' meaning 'marigold' or 'cup'. People named it this because the bright yellow flowers look like small golden cups in wet places, so today Caltha refers to that group of marsh marigolds.
