Taxonomic notes: Material from the Northern Flinders Ranges and Kangaroo Island will be described in the Flora of Australia, vol. 3, as 2 new subspecies. In both, the cones and articles are usually coarser than in typical A. muelleriana, and the phyllichnia margins are never raised. Cones are sessile or on a short peduncle to 3 mm long in the Flinders Ranges material, whereas cone peduncles are long (8-17 mm) and thicker in material from Kangaroo Island.
