Abstract
The oldest anatomically preserved and physiologically apparently independent gametophytes are described from the Lower Devonian of Scotland. These gametophytes have upright, leafless axes with terminally borne, bowl-shaped game-tangiophores. The antheridia are stalked and their walls are multicellular. The archegonia are clustered in groups on common bases.Year: 1980 PMID: 17820048 DOI: 10.1126/science.208.4441.295
