The article offers information on a study which assessed the relationships among the five sections of Typhonium sensu lato and its allied genera. A background on the plant genus Typhonium is offered. The phylogenetic relationships of Typhonium were analyzed using the combined DNA sequences of six chloroplast regions. Findings of the study suggest that Typhonium is not a monophyletic group and that Typhonium sensu lato may be subdivided into several monophyletic groups.

The article validates the new combinations wherein Typhonium s.l. was divided into four genera based on molecular phylogeny and morphology where Typhonium sections Diversifolia Scrinoonma et J. Murata, Pedata Sriboonma et J. Mura and Hirsuta Sriboonma et J. Murata were transferred to a generic rank. These new combinations include Typhonium diversifolium, Typhonium alpinum under Diversiarum and Typhonium hirsutum under Hirsutiarum.
