Barbeuia

 ( Endemic Flora Of Madagascar ) 

Barbeuia madagascariensis is a liana found only on the island of Madagascar.

Barbeuia has occasionally been placed in its own family, Barbeuiaceae. The APG II system of 2003, for instance, recognizes such a family and assigns it to the order Caryophyllales in the clade core eudicots, after Philippe Cuénoud sequenced a fragment of the Maturase K gene (extracted from a seed deposited in the Kew Herbarium) and showed that Barbeuia does not belong in Phytolaccaceae.Cuénoud P., Savolainen V., Chatrou L.W., Powell M., Grayer R.J., Chase M.W. (2002). Molecular phylogenetics of Caryophyllales based on nuclear 18S rDNA and plastid rbcL, atpB, and matK DNA sequences. American Journal of Botany, 89: 132–144. This represents a change from the APG system, of 1998, which did not recognize Barbeuiaceae as a family, for lack of molecular data.
