Morphology
This is a standard scientific binomial combining the genus name 'Conyza' (a flowering-plant genus) with the species epithet 'canadensis' (indicating origin from Canada), so the meaning is directly derivable as a Conyza species associated with Canada. Latin taxonomic naming is regular and cross-linguistically consistent, so a learner who knows both constituent meanings can infer the MWE's meaning.
Etymology
Conyza canadensis uses two name parts: Conyza, an old name for small, weedy, daisy-like plants, and canadensis, which means 'from Canada', so the full name simply marks it as a common North American weed.
