== Phylogeny ==
Comparison of homologous DNA has increased the insight in the phylogenetic relationships between the genera in the Haemodoroideae subfamily. The following trees represent those insights.<ref>{{cite journal|first1= Stephen D.|last1= Hopper|first2= Rhian J.|last2= Smith|first3= Michael F.|last3= Fay|first4= John C.|last4= Manning|first5= Mark W.|last5= Chase|year= 2009|title= Molecular phylogenetics of Haemodoraceae in the Greater Cape and Southwest Australian Floristic Regions|journal= Molecular Phylogenetics and Evolution|volume= 51|issue= 1|pages= 19–30|doi= 10.1016/j.ympev.2008.11.015|pmid= 19063982|bibcode= 2009MolPE..51...19H}}</ref>
