| Taxonomic list comments:From Wesley (1966, p. 128): "Summarizing the composition of the flora as a whole then we see that it is dominated by a variety of Bennettitales, with small-leaved conifers and plants with large, coriaceous leaves forming other major elements. Very much less strongly represented are the Caytoniales and the pteridophytes, while the evidence for the presence of ginkgophytes is very debatable. In addition, there are two unusual genera, Phyllotheca and Yuccites." | |
