Notes
A well circumscribed monophyletic genus with two species that was long treated as part of a widely circumscribed genus Gomphrena Mart. but resurrected by Pedersen (1990) because of its morphological distinctness (gamopetalous perianth, cauline leaves reduced to scales). Molecular phylogenetic analyses (Sage & al. 2007; Sánchez del-Pino & al. 2009) depicted Xerosiphon as isolated lineage in the gomphrenoid clade of subfamily Gomphrenoideae.A,B,C,D
