Morphology
The phrase combines the taxonomic headword 'genus' (a rank grouping related species) with the proper-name 'Xanthium' (the specific plant genus), so its meaning — the taxonomic group named Xanthium — is directly and transparently derivable from the parts. This follows common cross-linguistic scientific naming conventions where a category label plus a name denotes the group, so a B1 learner who knows both constituents would understand it.
Etymology
Genus Xanthium comes from an old Greek word meaning 'yellow', because some plants in this group have yellowish parts. These plants make sticky seed heads called burrs with hooked bristles that cling to animal fur, so the image of the burrs helps you remember this group of rough plants.
