Morphology

serotinous = serotiny (opaque) = serotin + ous

The immediate base 'serotiny' is a rare technical noun and the combining form 'serotin-' is not a productive, known English root, so adding '-ous' yields a specialised adjective that is not derivable by an average B1 learner.

Etymology

The word serotinous comes from Latin serotinus, from serus meaning 'late'. So, think of pine cones that 'wait' to open and only release their seeds later or after an event like a fire.
