Taxonomy

Within Durioneae, ''Kostermansia'' and ''Coelostegia'' form a clade that is sister to the clade comprising ''

s.s''. and '' Boschia'', which are some consider to comprise a single genus, and ''Cullenia''. Both of these clades form a clade that is sister to the remaining genus of the tribe, ''Neesia''. ''Camptostemon'' and ''Papuodendron'' are often included in this tribe as well. However, certain characters (pollen morphology, androecial vasculature, and wood anatomy, for example) support a closer relationship to the Malvoideae than to the Helicteroideae for these two genera. Durioneae has traditionally been placed within the

Bombacaceae Bombacaceae were long recognised as a family of flowering plants or Angiospermae. The family name was based on the type genus '' Bombax''. As is true for many botanical names, circumscription and status of the taxon has varied with taxonomic poi ...

because of the combination of monothecate anthers, smooth pollen, and tree habit. However, recent molecular evidence indicates that this tribe is most closely related to the tribe Helictereae of the traditional Sterculiaceae. In certain recent circumscriptions of the mallow family, the Bombacaceae and Sterculiaceae form an expanded family

that also includes traditional Malvaceae and Tiliaceae. In this circumscription of Malvaceae, the family is divided into 9 subfamilies and Durioneae is placed into the subfamily Helicteroideae, along with some of the members of the traditional Helictereae.
