Diagnosis
Large (up to 170mmlong and 74mm wide) microsporangiate pedunculate cones, appearing ‘segmented’ or organized into distinct layers in lateral outer surface view, built up of about 10 disc-shaped cone portions and a basal and apical cone portion with domeshaped apex and base respectively, gaps present between the layered portions. Peduncle robust, short, diameter about 1/3 of the cone diameter. Detached microsporophylls leave rhomboidal scars with a central impression of a possible vascular bundle. Individual cone portions found detached more or less trapezoid to diamond-shaped in cross-section with a longer and a shorter diameter and the cone axis subcentrally; outer margins frequently arc-shaped in crosssectional view. Slender, wedge-shaped microsporophylls, in dense facetted arrangement, generally in helical phyllotaxis; particularly each cone portion with 2–4 levels of microsporophylls, in alternating positions in adjacent levels. Each microsporophyll with 10 or more longitudinally running resin canals. In situ pollen of Eucommiidites-type, boat-shaped, ‘trisulcate’, surface finely perforate, smooth to microrugulate; microfossulae between perforations.
