What is another word for indusium?
Pronunciation: [ɪndjˈuːsi͡əm] (IPA) 
The indusium is a membranous covering found on the undersides of fern leaves, protecting the reproductive structures beneath. However, there are a few synonyms that can be used to describe indusia, such as a shield, a cover, or a veil. The term veil is particularly relevant as this covering can resemble a thin transparent layer that partially obscures the structures beneath. Similarly, shield refers to the defensive nature of the structure, protecting the delicate reproductive components from damage and ensuring their successful development. The word cover is a more general term that can refer to any type of protective layer, but in the context of indusium, it accurately conveys the function of the structure.
