Morphology

genus + Erwinia

The phrase is directly compositional: 'genus' (a biological rank) combined with the proper name 'Erwinia' denotes the taxonomic group called Erwinia. This follows standard scientific naming patterns that are cross-linguistically transparent, so a learner who knows both constituents will understand the meaning.

Etymology

Genus Erwinia comes from the surname of a plant scientist, Erwin F. Smith, who studied bacteria that harm trees and crops. So Erwinia marks a group ('genus') of bacteria known for causing plant diseases.
