Notes

Hartmann (2001b) treated Ruschianthemum as a distinct genus with R. gigas (Dinter) Friedrich as the only species. However, the species had already previously placed in Stoeberia because of strong similarities; it differs mostly in its fruit morphology, which has traditionally played an important role in delimiting genera in Aizoaceae. However, fruit characters have recently been shown to be far more homoplasious than previously expected (Klak & al. 2013), suggesting that fruit morphology on its own does not justify the recognition as a distinct genus. Given the large overall similarity in all other morphological characters to Stoeberia, this species has been re-instated as a member of Stoeberia by Chesselet & van Wyk (2002), based on very similar arguments.
