Dipentodon is a
genus of
flowering plants in the
familyDipentodontaceae. Its only
species, Dipentodon sinicus, is a small,
deciduoustree native to southern China, northern Myanmar, and northern India.[2] It has been little studied and until recently its affinities remained obscure.
Dipentodon was named and first described in 1911 by
Stephen Troyte Dunn in what is now called the
Kew Bulletin.[4] At that time, Dunn wrote:
The name Dipentodon, proposed for it, refers to the most remarkable character possessed by the flowers in the exact similarity of the calyx teeth and petals (if I rightly call them so) and their insertion so nearly in one whorl that the appearance is given of a ten-toothed perianth.
Dipentodon was placed in its own family by
Elmer Drew Merrill in 1941,[5] but this placement was not generally followed. Instead, most authors put Dipentodon in the ill-defined and heterogeneous family
Flacourtiaceae.[6][7][8] In the twenty-first century, Flacourtiaceae is recognized by only a few
taxonomists,[9] and then only in a much narrower
sense than it had been.[2][10]Dipentodon is unrelated to Flacourtiaceae
sensu stricto, a
segregate of
Salicaceae.[11][12]Molecular phylogenetic studies have led to the widespread acceptance of the family Dipentodontaceae and its placement in the order
Huerteales.[3] Some authors have defined the family as consisting only of Dipentodon.[13] Others, following the recommendation of a 2006
study,[14] have included Perrottetia.[2][15] When the
APG II classification was published in 2003, the
taxonomic position of Dipentodon was still unknown and it was placed
incertae sedis in the
angiosperms. It was listed in the appendix under TAXA OF UNCERTAIN POSITION.
