Mosses 蘚 (Bryophyta)

Polytrichum 金髮蘚/Pogonatum 小金髮蘚

sporophyte with a long seta

  • Hairy calyptra is derived from the archegonium and protects the developing capsule [left]. After the removal of calyptra, the capsule with operculum (lid) can be observed [middle]. At maturity, the operculum dries and detaches from the capsule, exposing the peristome and epiphragm to release spores [right].
