). The specimens from Catefica are often strongly compressed and lignitised. Internal details are known from only a few specimens. It is possible that the material represents more than one species, but the information currently available does not warrant recognition of several taxa. Differences in size may be attributed to differences in maturity as the floral structures appear to be preserved at different post-anthetic stages. The fruits/ovaries are obovate in longitudinal view, triangular in transverse section with rounded to sharp edges (
