Delimitation of the Phytolaccaceae has long been a matter of debate. The circumscription of the family followed here, except for the inclusion of Gisekia, parallels that of J. W. Nowicke (1969). In narrower concepts, such as that of G. K. Brown and G. S. Varadarajan (1985), which rely heavily on chromosome and distribution data, six segregate families are recognized, those of concern for the flora being Phytolaccaceae sensu stricto (Gisekia, Phytolacca), Petiveriaceae (Petiveria, Rivina, Trichostigma), and Agdestidaceae (Agdestis).
A. Cronquist (1981) wrote that “each of the several segregate families … appears to be a natural group, but collectively they all hang together with the rest of the Phytolaccaceae. I see no reason why they cannot be accommodated at the level of tribes or subfamilies.” For Agdestis, recent anatomical data support Cronquist’s assertion, favoring the retention of the genus as a monogeneric subfamily within Phytolaccaceae sensu lato (S. Carlquist 1999). Wood and stem data do not strongly support separation of Petiveria and Rivina from Phytolaccaceae (S. Carlquist 1998).
The manifold folk medicinal uses of our genera (except Agdestis and Gisekia) are summarized in J. F. Morton (1981).
Phaulothamnus, included in Phytolaccaceae by some authors, is treated in the flora in Achatocarpaceae [see page 12].
