Note: Lophopappus is rather similar to Proustia but differs in its solitary or few, grouped capitula, the lack of terminal spines on short branches, to some degree corolla colour (white in Lophopappus, pink or purple in Proustia), and the setulae on the achenes of Proustia, when present, are long, twisted or spiralled twin-hairs. Preliminary molecular work (Funk et al. pers. comm.) supports their separation, although they are clearly closely related. Teller a et al. (2003) have shown that pollen characters cannot usefully separate the two genera.
