| M. D. Brasier et al. 2012 | Frond unipolar, comprising two rows of first-order branches arranged in subparallel series that alternate either side of a stem exposed along the central axis (Figs 6A–B and 8A). Inflation of first-order branches is proximal, while that of second-order branches appears moderate to medial. Mature first- to third-order branches are displayed and not furled or rotated. A basal disc is sometimes preserved. |
