sponds to the persistent portion of the pseudo-peltate sporophyll-base, shows 
only a membrane limiting a mass of mucilage. The vascular bundles on

their way out to supply the sporophylls of this whorl (a) are seen on the 
corresponding radii in the cortex. 
The second transverse section (fig. 4) follows the plane marked by the 
line B B in fig. 1 . It cuts the cone nearer to its base in the plane of the 
“ pedicels ” of the sporophylls ( b ), to which the sporangia shown in fig. 3 
belong. The five sporophylls are seen radiating from the axis, and within 
each is its leaf -trace. The sporophyll widens out at the extremity of the
