Morphology
Gymnosporangium + juniperi-virginianae
This is a specialized scientific Latin binomial; its parts are taxonomic morphemes (and one element is not even a dictionary word), so a B1 learner who 'knows' the listed constituents would not be able to infer the specific meaning 'a rust fungus that causes cedar-apple rust'. Although such names are consistent across languages for specialists, their morphological components are not transparently meaningful to general learners, making the expression unintelligible without prior exposure or specialist knowledge.
Etymology
Gymnosporangium juniperi-virginianae may get its name from how it looks and where it lives: Gymnosporangium points to 'naked spore' because it makes orange, jelly-like horns that show its spores, and juniperi-virginianae names its common tree, the 'Virginia juniper'. So the name helps you remember that this rust fungus makes bright, exposed spore growths on junipers and causes orange-brown spots on apples and pears.
