Morphology

Pellaea + atropurpurea

This is a Latin scientific binomial rather than a compositional English phrase: while a learner who knows 'Pellaea' might guess it refers to a type of fern, the specific epithet 'atropurpurea' is not an English word and provides no predictable meaning to a B1 learner. Scientific names function as labels and the overall species identity and properties are not derivable from everyday English vocabulary, so the expression is not transparently interpretable.

Etymology

Pellaea atropurpurea gets its name from two parts: Pellaea, a small rock-loving fern, and atropurpurea, which means 'dark purple'. The name gives a clear picture of a little fern with dark, shiny leaf stems that lives on cliffs, so the words help you remember how the plant looks and where it grows.
