SPECIES, AUTHORITY D. bhardwaji (Varma & Rawat) Kalgutkar & Jansonius 2000
LOCATION (Varma & Rawat) Western and eastern India, including oil exploration areas in West Bengal and Assam; geographically the areas are about 1440 km distant from each other.
ORIG DESCRIPTION* Grains 2-porate, isopolar, somewhat barrel-shaped (about 40 x 61 x 40 µm), slightly constricted in the middle, dark brown. Pores at the lateral ends, circular (about 7.1 µm). The sexine forms a hemispherical to cone-like structure around the pore areas. It is provided with a circular outer opening communicating with the inner part of the aperture. Exine psilate, about 1 µm thick, consisting of sexine and nexine.

In the middle of the grain is a septum traversing the whole width of the grain. It shows two triangular flanges, generally directed towards one of the sides of the grain (perhaps due to greater pressure in one direction during preservation). The bases of the flanges are approximately of the same size. They meet near the middle of the septum, as can be seen in the pollen grains in lateral view. These triangular outgrowths may or may not be always equal and similar in shape. Numerous irregular folds are present on the general body of the grain.

K&J REMARKS The median septum confirms a fungal affinity. Clarke (1965), while pointing out the flanged central septum, suggested a reexamination of the type material to determine if the species should be transferred to the genus Dyadosporites.
