Morphology

Diplopterygium + longissimum

This is a Latin binomial (genus + specific epithet) rather than a normal English multiword phrase; the components are specialized/scientific (one not even in the dictionary) and the full descriptive meaning (a large scrambling fern forming extensive patches up to 18 ft) is not derivable by a B1 learner from the parts. Even if a learner guessed that 'longissimum' relates to 'long', the taxonomic name does not transparently convey the species' size, habit, or habitat, so the meaning is unpredictable for learners.

Etymology

Diplopterygium longissimum comes from old word parts: diplo- meaning 'double', -pterygium meaning 'wing', and longissimum meaning 'very long'. The name paints a picture of a fern with long, wing-like leaves often in pairs that spread into large patches, which fits this species that makes very long fronds and covers wide areas.
