Tectum usually psilate, sexine reticulate, granulate or striato-reticulate, usually with OL or obscure pattern, 1-2 µm thick, nexine 1-1.5 µm thick. Most striking variation is found in the shape class, aperture type and tectal surface. The brief characteristic features of all members described in this work have been tabulated in Table-1.
