A very nearly allied species to this, if not the same, differing only in the more acuminated pinnæ, is No.
12S7 of Mr Cuming’s collection from Columbia. In our Mexican specimens, probably from not being submitted
to pressure wlien freshly gathered, the rachis is incurved, and all the pinnæ refracted, so that they all
point to one side. The fructifications are so sunk into the frond, as to give a tuberculated appearance to the
anterior surface.
