12. Mecardonia Ruiz & Pav.

Ten species, North America, South America, Caribbean Islands.

Steyermark (1963) and many earlier authors treated Mecardonia as part of the genus Bacopa. Pennell (1946) provided a lucid discussion of the problems associated with generic limits in the group and concluded that Mecardonia was not, in fact, very closely related to Bacopa. The two genera differ in a suite of floral characters, as well as in the kinds of secondary compounds produced.
