Selaginella harrisiana ap. nov. is described from the Permian (Kungurian) Upper Coal Measures at Victoria Pass, N.S.W. It resembles Selaginella selaginoides in its leafy parts but has a long leafless rhizome recalling Asteroxylon. The present evidence suggests that the herbaceous and arborescent ly copsids are taxonomically remote.
