Biology:
D. crassifolium subsp. crassifolium occurs in South Africa. D. australe (Aiton)J. Black (= Mesembryanthemum australe Aiton) has been shown by Chinnock (1971) to be confined to New Zealand.
Taxonomic notes:
*This contribution has been made by R. J. Chinnock, State Herbarium of South Australia: Disphyma crassifolium (L.)L. Bolus subsp. clavellatum (Haw.)Chinn., comb. nov. Basionym: Mesembryanthernum clavellatum Haw., Misc. Nat. 79 (1803). The greater variation in seed characters of D. clavellatum than originally thought (Chinnock, 1971) falls within the limits of the African species, D. crassifolium, and the other differences between the Australian and African populations are only considered to be subspecific.
