Morphology
Bidens + bipinnata
This is a Latin binomial: knowing 'Bidens' as a botanical genus allows a learner to infer it names a species (i.e., a plant in the Bidens genus), but 'bipinnata' is a Latin epithet that a B1 learner will not parse to recover the descriptive meaning (yellow flowers, bristly seeds). The taxonomic relation is therefore partially transparent across languages, but the specific descriptive content is not derivable from the constituents.
Etymology
Bidens bipinnata comes from Latin parts bi- and dens, meaning 'two teeth', and from bipinnata, meaning 'twice divided'. The 'two teeth' image refers to the plant's seeds, which have two little hooks that grab onto fur or clothes, so the name helps you remember a yellow-flowered plant with sticky seeds.
