Morphology
Centaurea + nigra
This is a scientific binomial (genus + Latin specific epithet) and the second constituent 'nigra' is not an English dictionary word here, so a B1 learner who only knows the listed constituents would not be able to infer the common-meaning 'black knapweed' or recognize it as a plant species. The term relies on specialist botanical knowledge and Latin morphology rather than ordinary compositional English, making it unpredictable for typical learners.
Etymology
Centaurea nigra gets its name from a Greek story: Centaurea points to the 'centaur' Chiron, who was said to use plants to heal, so the flower was named after that healing image. The Latin word nigra means 'black' and refers to the dark centre of the purple flower, which is why the plant is also called 'black knapweed' today.
