Fig. 2.14 a–c Proximal view showing highly dense sculpture obscuring laesurae and spore outline.
Cavate form just visible
Description: Cavate. Trilete. Amb triangular, rounded-triangular to sub-circular.
Laesurae not distinct but when visible long and extending to equatorial margin of
the spore. Sculpture of ektexine complex; essentially composed of long baculae to
pilate processes which fuse frequently at their base. Sculptural elements densely
spaced, irregular in size; their length varies according to the state of preservation,
often with broken ends.
Dimensions: 33–60 µ in equatorial diameter (30 specimens measured).
Reconstructed spore showing the distinct cavate morphology of the spore and the
interconnected projections making the sculpture.

different samples, ranging in age from Sakmarian to Upper Permian of Collie,
