FIGURE 5. Carpocladus fertilis Vervoort & Watson, 2003. A. Proximal most part of a phylactocarp, showing the proximal most cladial cormidium, the proximal nematothecate internode, and the first regular rachial internode with male gonotheca, bifid costa and axillar hydrotheca. B. Detail of the origin of a phylactocarp, showing the proximal most cladial hydrotheca, its lateral apophysis, the first (nematothecate only) rachial internode, and the first regular rachial internode. C. Detail of the branching site of a costa, showing the axillar hydrotheca, the peculiar position and shape of its mesial nematotheca, and the apophysis supporting the frontal branch of the costa. D. Nematothecae of a costa. E. Detail of the aperture of a male gonotheca. Scale bars: B–E = 200 µm; A = 500 µm.
