Morphology

helianthus + laetiflorus

This is a Latin binomial: 'Helianthus' clearly identifies the sunflower genus so a learner who knows the constituents can infer it denotes a species of sunflower. However, the specific epithet 'laetiflorus' has no dictionary gloss here and does not transparently yield the detailed traits in the full definition, so the meaning is only partially predictable.

Etymology

Helianthus laetiflorus comes from old Greek and Latin words: Helianthus means 'sun-flower' because these plants turn toward the sun, and laetiflorus means 'bright-flowered' for its cheerful yellow heads. So the name gives a clear image of a tall, sunny sunflower with large, bright blooms.
