(a–g) Mtshayelo kougaensis gen. et sp. nov., (h–i) Yarravia oblonga, (j–k) incertae sedis bilobed sporangia. (a) AM 7999a. Scale = 1 cm. Holotype. Bifurcating naked axis terminated by two synangiate structures. (b) Detail of AM 7999a. scale = 5 mm. Two synangiate structures. (c) Detail of AM 7999a. Scale = 5 mm.
