AWealden and Lower Cretaceous species^ (figs. 601, A—C; 602) repre- sented in several European localities, also in North America and Japan, reaching a length of over 70 cm.; in habit very similar to Ceratozamia mexicana, Macrozamia Macleayi and some other recent Cycads. The rachis has a fairly broad median groove on the upper surface; pinnae alternate, opposite or sub-opposite, from 3 to 20 cm. long and from 1-5 to 2 cm. broad, linear, generally narrowed towards the base, but in the more slender segments the re- duction in breadth is less obvious; attached obliquely to the rachis, shghtly thickened and broadened at the base (fig. 601, C), separated from the rachis by a distinct absciss- layer and leaving an elliptical scar; usually inclined at about 45° but.
