Species

The Genus Dahlia was split into 4 sections by Paul Sorensen in 1969 and we use this below to separate the species dahlias as it is and easy system to use however Dayle Saar’s recent work has shown that section Pseudodendron and section Dahlia are genetically a section and are only divided at clade level. while section Epiphytum is not valid and belongs with Pseudodendron and some members of the Dahlia section in the variable root clade.
