Abstract

Austroannularia gen. nov. is proposed for species of morphologically asymmetrical sphenopsid leaf whorls similar to those included in the Cathaysian genus Lobatannularia, but lacking the strongly bilobate character of the latter genus. The two species, A. subcircularis sp. nov. from eastern Australia and A. qubuensis from southern Tibet (Xizang) occur in Permian non-marine strata containing typical Gondwana species in the absence of Cathaysian species.
