Morphology

indusial = indusium (semi-transparent) = indusium + al

The adjective is a regular formation from the specialized noun 'indusium', but the technical base word and slight stem change make it less immediately accessible to learners.

Etymology

Indusial comes from the Latin word indusium, which meant 'a covering' or 'garment' and from a verb meaning 'to put on'. So indusial describes a small protective 'cover' or 'coat' that sits over parts of a plant or animal.
