Morphology

foliaceous = foli + aceous

Although the scientific sense is still leaf-related, the classical morphology is not obvious to an average learner and the meaning is not predictable from the surface form alone.

Etymology

Foliaceous comes from the Latin root foli- meaning 'leaf', like in foliage, so geologists use it for rocks and minerals that form thin, flat layers that look like leaves.
