A bract (PO:0009055) that subtends an archegonium (PO:0025126). [source: ISBN:0962073342]
Comment
When an archegonium occurs on a specialized lateral branch of the gametophore, all of the phyllomes on that branch are usually perichaetal bracts. If an archegonium occurs on a main axis of the gametophore, only the terminal phyllomes are usually perichaetal bracts. The two or three terminal-most perichaetal bracts may fuse to form a gametophytic perianth.
