Taxonomy
In Apg3 classification Malvales is mostly treated as one family Malvaceae. This is due to the fact that many of the traditional families in Malvales had species form other families of Malvales in them. There was quite some confusion about the delineation of the Families.
In recent research the delineation has become more clear.
More specifically the family of Byttneriaceae has many species coming from the Sterculiaceae: Abroma, and Theobroma.
In the Plant theory the clades in Malvales are treated as Families in the order of Malvales, instead of Subfamilies in the Family Malvaceae. Bytt
Helicteriaceae is treated a subfamily of Malvaceae, Helicteroideae. In older taxonomies many genera were included in Bombacaceae.
In the first version of the Plant theory Helicteriaceae was treated as a family and placed in Subphase 6.
In the update Byttneriaceae is split of from Grewiaceaee and Placed in Subphase 6. Helicteriaceae is included in Byttneriaceae
