The genus Agrostocrinum F. Muell. is reviewed. Two species are recognised, A. hirsutum (Lindl.) Keighery and A. scabrum (R. Br.) Baillon, both confined to southern Western Australia. A distinctive inbreeding maritime race of the latter, found in scattered populations on granites along the south coast, is described as a new subspecies, A. scabrum subsp. littorale Keighery.
