This paper presents a phylogenetic analysis of Zingiberales based on 613 parsimony informative characters of the plastid matK gene, the trnL-trnF region, the rps16 intron, and a conservative part of the nuclear ribosomal ITS region (part of the 18S, 5.8S, and 26S rDNA).

An equally strongly supported clade within the Bornean group contains the species distributed in Sabah (Malaysia) and Brunei.
