Discussion

Species 1.

Bontia is monospecific and the only genus of Myoporeae (the former Myoporaceae) native to the Americas. Phylogenetic analysis suggests that it was derived from within the Australian genus Eremophila R. Brown and achieved its current distribution via long-distance dispersal (S. A. Kelchner et al. 2001).
