Species 1: w United States.
Although the floral morphology of Bensoniella is quite distinctive, vegetative similarities suggest a connection with the otherwise equally distinctive genus Mitella. Molecular data (D. E. Soltis et al. 1990), as well as karyotype analysis (Soltis 1988), clearly show a close relationship between the genera.
