As described here, Mesembryanthemum is the narrowly delineated genus sensu H. M. L. Bolus (1928-1958, part 3, p. 164, fig. 25) .

The ability of Mesembryanthemum crystallinum and M. nodiflorum to accumulate and release salt into the surrounding soil is one mechanism by which these species dominate disturbed areas (N. J. Vivrette and C. H. Muller 1977; N. J. Vivrette 1980) .[1]
