A chiefly Central and Southeast European group with four to 16 species depending on species delimitations (Frajman & Oxelman 2007). Heliosperma has been conserved over its senior synonym Ixoca (Barrie 2011), as proposed by Frajman & Rabeler (2006). Frajman & al. (2009b) analyzed several independent nuclear and plastid loci showing strong support for monophyly of the genus, although it appears to have a complex history, possibly involving ancient hybridization events.
