  • APC Comment: Chapman, APNI: 1918 (1991) listed a "Macrozamia spiralis var. diplomera Benth., nom. illeg, non A.DC." Bentham clearly referred to "F.Mueller" and cited one of the same syntype collections "Castlereagh River, C.Moore" cited by Mueller (1866). This name should therefore be considered merely a later usage of M. spiralis var. diplomera F.Muell. and not an illegitimate later homonym.
