Trilete sporomorphs from Australian Permian sediments

Abstract

This paper, in conjunction with two earlier publications by the same authors (Balme and Hennelly 1955, 1956), completes the taxonomic revision of a number of the common sporomorphs occurring in Australian Permian sediments. Twenty-six sporomorphs bearing triradiate tetrad scars are illustrated and described, the majority being assigned to existing genera of Palaeozoic fossil spores. Two new organ genera, Tholosporites n. spt. and Bascanisporites n. spt. have, however, been created to receive morphological categories differing from any previously described. A short discussion on the distributions and possible affinities of the sporomorphs treated is included.
