Arisema triphyllum consists of 4 subspecies, officially classified during the 1949 and updated in the 1981 by using morphological data. They were observed cross breeding across their typical geographical locations, meaning they do not have much reproductive isolation creating many hybrids. Despite the abundance of hybrids, they subspecies are still readily distinguishable from one another. In recent years, research using molecular data has shown to be much more statistically effective at representing the relationships between species. Their distinct morphological features, and molecular data collected from various intron sequences, has revealed the phylogenetic relationship between the subspecies. With the expansion of the field molecular phylogenetics the analysis of this species nature leads to a better understanding of the relationships within the complex and support to end the erroneous use of the term subspecies as a significant taxonomic status. By comparing multiple genetic loci, specifically intergenic spacers ITS and rpl12-rpc20, the phylogeny created shows little genetic variation within the species complex.
