'''Dipentodontaceae''' is a [[monotypic]] family of [[flowering plants]] that contains a single [[genus]], '''''Dipentodon''''', and a single species, '''''Dipentodon sinicus'''''. It is a subtropical and tropical family of deciduous small trees or shrubs native to northeast [[India]], southern [[China]] and [[Burma]]. The plants have simple leaves with toothed margins and are attached alternately to stems. The flowers are in axillary umbels of 25-30 small regular flowers with a calyx of 5-7 united sepals, a corolla of 5-7 free or united petals, with 5-7 stamens, and sometimes 5-7 stamenoids in addition, and with 3 united carpels. The fruit is a late dehiscing capsule.
This family is recognized by many taxonomists. However, the [[APG II system]] (2003) does not recognize such a family and leaves the genus ''Dipentodon'' unplaced as to family, or any other grouping. This represents a slight change from the [[APG system]] (1998), which did recognize the family but did not place it either. The family consists of a single species ''Dipentodon sinicus'', occurring in China and neighbouring parts of Asia.
The [[Cronquist system]] (1981) also recognized this family but placed it in the order [[Santalales]] in subclass [[Rosidae]]. The [[Takhtajan system]] (1997) placed the family in his [[Violales]] (= [[Malpighiales]]), while others recognised a Dipentodontales in Dilleniidae. Peter Stevens of the Angiosperm Phylogeny Website places the family in the order [[Huerteales]].<ref>{{zh icon}} Wu, Lu, A.-M., Tang, Y.-C., Chen, Z.-D., & Li, D.-Z. (2002).
