Morphology

Klamath + weed

The noun 'weed' clearly signals the semantic category (a wild/unwanted plant), but 'Klamath' is a place-name/proper noun with no compositional lexical meaning for most learners, so the phrase only tells you it is a particular weed associated with Klamath rather than giving the specific botanical sense. This makes the expression partly transparent (you can infer it is a type of weed) but not fully predictable or informative about species or properties.

Etymology

The plant name Klamath weed may come from the Klamath area in the western United States, where the bright yellow flower was first noticed spreading through fields and pastures. Because it quickly took over grazing land, people used weed to mean a 'harmful plant', and that name stuck.
