Morphology

helianthus + petiolaris

This is a Latin binomial (taxonomic) name rather than a normal English phrase; as a proper name it labels a particular sunflower species and does not follow standard English compositional patterns. The second element 'petiolaris' is not an English word (and not defined here), so a B1 learner who only knows the listed constituents would not be able to derive the species meaning from them.

Etymology

Helianthus petiolaris comes from older Greek and Latin words: Helianthus means 'sun' + 'flower' and petiolaris means 'little leaf stalk'. So the name shows a 'sun-flower' with 'little leaf stalks', which helps you remember it is a kind of sunflower with thin, branching stems.
