Discussion
Species 120 (1 in the flora).
Drosanthemum speciosum (Haworth) Schwantes was misapplied by P. A. Munz (1974). The taxon in question is Malephora crocea (Jacquin) Schwantes (W. R. Ferren Jr. et al. 1981). Drosanthemum speciosum is cultivated as an ornamental in California; it is not known to naturalize. For an illustration of Drosanthemum speciosum see H. Herre (1971). Drosanthemum is closely related to Delosperma though the latter genus lacks membranes covering the seeds.
