DESCRIPTION Triletemicrospore.Ambcircular.Thelaesuraecannotbe clearly seen; they seem short and raised in a very small contact area.The two faces are densely covered by more or less short and sinuous rugulae topped by bacula, coni, spines or tubercules ( 4 to 7 µm high), giving to the spore a bristling appearance. The exine is about 3 µm thick. Equatorial diameter = 35-45 µm . REMARK The ornamentation of Neoraistrickia sp. 3 has similarities with that of N. sp. 2, but can be distinguished from the later by its dense and bristling appearance and its thicker exine.
