PHYLLOCLADUS:— 



Fig. 51. Phyllocladus protractus; a, lateral, longitudinal view of a pollen 

 grain (x 500) with the proximal face covered by a "saccus" (z), possibly 

 an artificial feature resulting from the loosening of the sexine from the 

 nexine; b, g, lateral (longitudinal and ti'ansverse) view (surface); c, f, same 

 as b and g, in optical section; d, distal face ( x di = distal pole); e, proximal 

 face (x pr = proximal pole). — b-g x 1000.
