Fig. 2.17 a Distal view. b Proximal view. c Echinate cingulum, a characteristic of this species
Fig. 2.18 a General view showing cingulum and folds along laesurae and intra-punctate structure
(immature spore). b Structure and reduced sculpture in immature spore. c Mature spore with welldeveloped echinate sculpture and wide cingulum. d Mature spore; wide bases of spines and wide
cingulum, torn in parts. e Mature spore; spine tips broken, only bases left which have the appearance
of pseudo-verrucate sculpture. Immature spore
to the immense variability of the sculpture, as also evident from the present
study (Fig. 2.17). Immature spores display subdued sculpture while mature spores
are characterised by coarse sculpture and a wide cingulum, which is often torn
(Fig. 2.18).
Genus Gondisporites (Bharadwaj 1962).
Diagnosis: Cavate and zonate. Trilete; laesurae long. Amb rounded-triangular.
Ektexine sculptured and structured. Sculpture echinate. Structure intra-punctate
