  • THE late Silurian–early Devonian genus Cooksonia, characterized by smooth isotomously branching axes and solitary, terminal sporangia1, has long been regarded as the archetypal vascular plant because of its age and simplicity of organization. The discovery of stomata, sterome2 and thick-walled spores1,3 in Cooksonia pertoni and C. hemisphaericaconfirmed its land-plant status, but tracheids have never been demonstrated in attached axes4. Here we report on tubes with differentially thickened… CONTINUE READING
