%X The structure and distribution of bisaccate microspores isolated from coals and shales of the Australian Permian are discussed. Microspores assigned here to the sporotypes Lueckisporites Potonie &amp; Klaus, Alisporites Daugherty, Florinites Schopf, Wilson, &amp; Sentail, and Pityosporites Seward have been described and a number of new sporomorphs designated. Vestigisporites n. spt. is instituted as a new sporotype. Comparisons are made between Australian Palaeozoic bisaccate forms and similar types from approximately contemporaneous deposits in other parts of the world, and the possible affinities of early two-bladdered microspores discussed.
