2 Systematic Descriptions
Genus Potoniesporites (Bharadwaj 1964a, b).
Diagnosis: Monosaccate, bilaterally symmetrical. Amb oval to sub-circular.
Monolete; proximal scar not always clearly visible. Corpus outline circular,
sub-circular or rhomboidal. Corpus ektexine smooth or structured, detached
equatorially on proximal face and intra-equatorially on distal face.
Known distribution: Upper Carboniferous to Permian of Northern and Southern
hemispheres.
Discussion: Potoniesporites was first described from the Carboniferous of the
Saar. Bharadwaj described the genus first in 1954, and emended it in 1964 giving a more detailed description and emphasising the ‘cappula’ or ‘distal zone’ in
