Morphology

periclinal = clinal (opaque) = peri + clin + al

The term is a specialized technical adjective in botany/geology and the components ('peri-' and 'clin-') are not familiar to average B1 learners, so the precise meaning 'parallel to the surface' is not derivable.

Etymology

Periclinal comes from peri- 'around' and cline 'to lean', the same idea you see in incline. So a periclinal surface or cell wall 'leans' around the outer surface and is therefore parallel to that surface.
