Calyptra - Calyptra (English spelling)

It is an organ that protects the sporophyte of moss plants, and is a modified archegonia that develops with the development of the sporophyte. In mosses, as the sporophyte grows, the upper half of the calyptra becomes a cap, which is often attached to the capsule.
