...PLATE 1 All figures are approximately x1000 unless otherwise stated. All photomicrographs were taken in plain transmitted light. The specimens are all from sample RKSL 50, collected from the Middle Bhuban Formation (Middle Miocene) of the Rengtekawn–Sherlui footpath/road traverse, Mizoram...

.... The scale bar represents 20 μ m in all figures. The number of verrucae/knobs was given as eight or nine in the description of the form genus Mediaverrunites in Nandi and Sinha (2007) . However, the type species, Mediaverrunites mulleri , was described as having either four or more than eight...

... Amazonia has a palynological assemblage comparable to the one studied herein. Nogueira et al.
