For the genus of moth, see Calyptra (genus).

In bryophytes (especially mosses), the calyptra is a cap of gametophyte tissue that protects the sporangium. This cap is lost when the sporangium capsule is mature and ready to release the spores. In flowering plants, the calyptra is a covering tissue for stamens and carpels. The name is also used for the capping tissue of roots.
