 (X 1000) exhibit grains in lateral view with (in A-C, and F-H) the distal 

 pole at the top. An aperturoid spot is faintly marked in the upper left-hand 

 (luadrant in D. The detail figures show the exine stratification enlarged 

 2000 times. The detail-figures between the main figure and the LO-patterns 

 in E show an irregular grain (upper detail-figure) and an opened grain 

 (both X 250). H is a Fitzroya pollen grain of ± normal type whereas in G 

 a deviating, ± "subsaccate'"' gi'ain is shown. — Pollen grains of other cupres- 

 saceous plants are shown in Figs. 4 {Actinostrobus), 11 (Callitris), 29 (Diselnm),
