Caliptra

The term caliptra comes from the Greek kalýptra, derived in turn from kalýptō which means hide.
With the term caliptra, in botany, we mean some fabrics with particular functions:
– Coating, which covers the apex of the roots like a cap with a protective function of the apical meristem. (Sin. Pileoriza or Cuffia);
– In bryophytes it is the enlarged portion of the archegonium that surrounds the sporophyte in its development;
– In some flowers (Eucalyptus) it is the cap that covers and preserves the stamens formed by pieces of the perianth.
