Morphology

helianthus + angustifolius

The binomial is compositionally transparent in morphology: 'Helianthus' denotes a sunflower and 'angustifolius' (Latin angust(i)- 'narrow' + -folius 'leaved') yields 'narrow-leaved', so a speaker who knows both constituents would derive 'narrow-leaved sunflower'. However 'angustifolius' is a Latin botanical epithet not found in the learner dictionary and is unlikely to be known by a typical B1 learner, so the meaning is not fully accessible without specialized/Latin knowledge.

Etymology

Helianthus angustifolius comes from old Greek and Latin words: Helianthus means 'sun-flower' and angustifolius means 'narrow leaves'. So, the name helps you picture a sunflower with long, thin leaves that often grows in wet places.
