Examples from the Web for indusia
The pairs of sori are covered with pairs of indusia which, on the maturity of the sporangia, open out opposite to each other.
The two plants might be difficult to distinguish were it not for the difference in their indusia.How to Know the Ferns|Frances Theodora Parsons
