Notes

Calyptridium is a North American genus with eight species (Guilliams 2009). Although Hershkovitz (1990) treats Calyptridium as a section of Cistanthe, phylogenetic analyses have shown that this consideration makes Cistanthe a non-monophyletic group (Hershkovitz & Zimmer 2000; Applequist & Wallace 2001; Hershkovitz 2006).
