Fig. 2.41 Corpus seems to ‘float’ within sac
Discussion: Wilson (1960) in his discussion of Florinites which resembles Densipollenites interpreted it as having the ektexine detached from the entire proximal face and attached only over the central area of the distal face. However,
Florinites differs from Densipollenites in being bilaterally symmetrical and possessing a smaller saccus, reflected by the absence of prominent folds in Florinites.
Bharadwaj noted the dense structural elements.
The irregular position of the corpus in Densipollenites as a result of the ektexine
being detached from the nexine (endexine) over the greater part of the corpus,
distinguishes this genus from Potoniesporites.
Densipollenites indicus (Bharadwaj 1962) (Fig. 2.41).
Occurrence: Found only in Lower Permian of Wilga Basin. Bore 3/80
, 110
, 189
.
Description: Monosaccate. Outline of corpus circular, varying in size. Tetrad mark
absent. Ektexine attached to nexine on one face. The rest of nexine is loose and
often folded or distorted. Structure of nexine granular, coarse, covering evenly
entire area.
Dimensions: 70–150 µ of total pollen grain; corpus diameter 25–105 µ (46
specimens measured).
