Species of Phemeranthus were considered as members of Talinum. However, morphological and molecular analyses have shown that c. 30 New World species that have terete to semi-terete leaves represent a lineage different from Talinum (Talinaceae; Carolin 1987; Hershkovitz & Zimmer 2000; Applequist & Wallace 2000; Nyffeler & Eggli 2010; Ocampo & Columbus 2010).
