Scale bar = 4 mm. Fig. 10. Apical part of an erect axis covered by hairs (paratype CAT! 71). Scale bar = 155 μm. Fig. 11. Apex of an upright branch showing the distichous pattern of division of the subapical cells (isoparatype BI! 38466). Scale bar = 30 μm. Fig. 12. Irregularly arranged outermost cortical cells in surface view (paratype CAT! 71). Scale bar = 8 μm. Fig. 13. Transverse section of a compressed upright branch; seven cells (axial and periaxials) are aligned along the major axis in an evident row (paratype BI! 38467). Scale bar = 50 μm. Fig. 14. Longitudinal section of an erect axis: elongated axial and periaxial filaments composing the medullary region are well distinct from the isodiametric subcortical cells (paratype BI! 38467). Scale bar = 50 μm. Fig. 15.Apical and lateral tetrasporangial sori inserted at 90º on the axes (paratype BI! 38467). Scale bar = 650 μm. Fig. 16. Stichidium-like tetrasporangial branchlets constricted at their bases and shortly stalked (paratype BI! 38467). Scale bar = 230 μm. Fig. 17. Tetrasporangial sorus with tetrasporangia regularly arranged in chevrons (6 per row) and a steril margin (paratype CAT! 71). Scale bar = 100 μm. Fig. 18. An empty sorus in surface view: in the gaps of the outer cortex the tetrasporangium basal cells are visible (arrow). Regenerated tetrasporocysts (arrowhead) (paratype BI! 38467). Scale bar = 60 μm. Fig. 19. Longitudinal section of tetrasporangial sorus along the medullary row of axial and periaxial filaments forming a cubic-mesh network (paratype BI! 38467). Scale bar = 60 μm.";
